Abstract:
We have considered two novel configurations for optical parametric oscillators (OPO’s): transversely-pumped counter-propagating and nondegenerate backward OPO’s due to the distributed feedback provided through the opposite propagation directions of the signal and idler. In both configurations, by changing the incident angle of the pump beam, one can tune the output frequency in a large range. The threshold pump powers for the oscillation can be as low as ~10 W for the transversely-pumped counter-propagating OPO’s and 44 W for the nondegenerate backward OPO’s. The quasi-phase matching is achieved by spatially modulating second-order susceptibility along the growth direction based on semiconductor alternating thin layers or asymmetric quantum-well domain structures or by electric-field poling in conventional second-order nonlinear materials. The nondegenerate backward OPO’s offer the most efficient conversion among all the configurations for the OPO’s having the same threshold pump power. The transversely-pumped counter-propagating OPO’s have the optimal pump power.

Abstract:
This thesis describes the design and implementation of several novel, nanosecond pulsed, intracavity optical parametric oscillators for the generation of terahertz radiation. The application of the intracavity approach in the context of terahertz optical parametric oscillators has been demonstrated for the first time, and the pump wave energy required was thereby reduced by an order of magnitude. The terahertz wave was tunable from under 1THz up to 3THz with a free running linewidth of ~50GHz and pulse energies up to ~20nJ (pulses were a few nanoseconds in duration). The terahertz beam profile was of Gaussian shape and could be focussed down to 2.3 times the diffraction limited spot size (M² values of 2.3 and 6.7 in the components of the beam parallel and perpendicular to the silicon prism array output coupler respectively). Developments of this intracavity source with regard to the linewidth are also reported. Implementation of etalons in the optical (laser and OPO) cavities was shown to be a promising technique that brings the terahertz linewidth down below 1GHz (close to the transform limit of nanosecond pulses) while retaining the tuning range and beam characteristics of the free running system. Close to Fourier transform limited pulses were obtained (<100MHz linewidth) via an injection seeding technique, although with significantly increased system complexity. A deleterious effect caused by the mode beating of a multimode host laser was also discovered, in that sidebands were induced on the seeded downconverted wave. This has wider implications in the field of intracavity OPOs. Finally, quasi-phasematching techniques implementing periodically poled lithium niobate were investigated as a way to lower the downconversion threshold energy requirement (by collinear propagation of the optical waves), and also to extract the terahertz wave rapidly from the (highly absorbing in the terahertz region) lithium niobate crystal. The existence of two phasematching solutions arising from the bidirectionality of the grating vector was identified as a serious design constraint in the context of an OPO where either solution can build up from noise photons, and so prefers the solution with the lowest walkoff of the downconverted waves - possibly resulting in unextractable terahertz radiation. Quasi-phasematching with an orthogonal grating vector (with identical but opposite phasematching solutions) was demonstrated and cascaded downconversion processes observed and characterised. These cascaded processes are permitted by the collinearality of the optical waves and may allow efficiency improvements through overcoming the quantum defect limit. This research has resulted in four peer reviewed papers in respected journals, and the intracavity terahertz OPO has been licensed to a company who have commercialised the technology (M Squared Lasers, Glasgow).

Abstract:
The all-solid-state (or "holosteric") optical parametric oscillator has resulted from the recent development of diode-laser-pumped solid-state lasers and from recent advancements in new optically nonlinear materials. As a result, all-solid-state sources of widely tunable (ultraviolet - visible - near infrared) coherent radiation are now possible by using the radiation from diode-laser-pumped solid-state lasers, either directly or after frequency conversion, to pump optical parametric oscillators. Such devices can be made compact, efficient and reliable. The work described in this thesis explores the feasibility of obtaining widely tunable radiation from such devices, with particular reference to low threshold, high efficiency operation, so requiring only modest energies (1 mJ in ultraviolet) from the pump source. In particular, a frequency tripled or frequency quadruped Nd:YAG laser pumped by pulsed, GaAlAs diode laser bars has been used as the pump source, and lithium triborate has been used as the nonlinear medium in the optical parametric oscillator. Two geometries of lithium triborate crystals have been investigated as the nonlinear medium. One was cut for a type II non-critical phase matching geometry, while the other was cut for a type I critical phase matching geometry. The oscillator cavities were designed for optimum focusing and mode matching aiming for operation with a low pump energy through the use of tightly focused pump radiation. The ultraviolet pump source was based on a Q-switched diode-laser-pumped Nd:YAG laser which generated pulses at 1.064 mum with energy 10 mJ and duration around 10 ns. These were then frequency up-converted to the UV at 355 nm or 266 nm, so as to be suitable for pumping the parametric oscillators. Generally, an overall conversion efficiency from 1.064 mum to 355 nm of >30% was obtained using the nonlinear materials potassium titanyl phosphate and lithium triborate for second harmonic generation and sum-frequency mixing respectively. For conversion to 266 nm, an overall efficiency of > 18 % was obtained using the nonlinear materials KTP and BBO for two step second harmonic generation. In the experimental investigations of the all-solid-state lithium triborate optical parametric oscillator pumped at 355 nm a low oscillation threshold was obtained in the type II non-critical phase matching geometry (around 0.2 mJ) and pump depletions of 50 % were obtained at around six times threshold. This device could be temperature tuned (20 - 200 °C) from 457 to 481 nm (signal wave) and 1.6 to 1.35 mum (idler wave). Optimised focusing conditions corresponding to the theory of Guha et al were approached in the type I phase matching geometry, and despite the existence of a 1° walkoff angle, the minimum oscillation threshold was measured to be around 0.3 mJ. Generally, pump depletions of about 35 % were obtained, at around four times threshold. These devices could be angle tuned (through crystal internal angle 14°) from 457 to 666 nm (signal wave) and 1.6 mum to 768 nm (idler wave). (The whole of the range 420 nm to 2.3 mum could be covered with such a device given additional mirror sets). The all-solid-state type II geometry lithium triborate optical parametric oscillator was also pumped at 266 nm, when it was temperature tunable (20 - 200 °C) from 306 to 314 nm (signal wave) and 2.03 to 1.75 mum (idler wave). Pump depletions of 25 % were demonstrated with this device at pump energies of four times threshold. In addition to the above experimental investigations, the thesis addresses the issues of (i) choice of nonlinear material for optical parametric oscillators in terms of appropriate figures of merit, and (ii) optimisation of pump and resonated wave focusing parameters. Reviews of the appropriate theoretical background to phase matching geometries and optical parametric interaction are included.

Abstract:
This thesis describes the development of a new generation of pulsed optical parametric oscillators (OPO's) based on two new non-linear materials, urea and beta-BaB2O4 (or BBO), and pumped by a new class of laser pump sources, namely, excimer lasers, to provide broadly tunable coherent radiation in new regions of the electromagnetic spectrum, particularly in the ultraviolet and the visible, which have previously been inaccessible. The laser pump source used during this work was a pulsed ultraviolet XeCl excimer laser operating at 308nm. Because of the stringent demands on the pump beam quality (with regard to both spatial and spectral coherence) for successful operation of OPO's, the pump laser was designed and constructed as an injection-seeded system, to provide a narrow-linewidth, near-diffraction-limited output beam, with sufficiently high peak powers to enable OPO operation. In this way, we were able to obtain an output beam with a linewidth ≤ 0.2cm-1, and a full-angle of divergence as low as 60muR (~3 times the diffraction limit). The maximum energy available from the pump laser was 30mJ, in pulses measuring typically 10ns in duration. The output beam was also linearly polarised to better than 95%, and the pulse repetition rate was 1 Hz. In the early part of this work, we used the constructed pump laser to investigate spontaneous parametric fluorescence in a home-grown urea sample, in order to characterise the crystal, and to compare the observed spectrum with the calculated OPO tuning curves. The results of these experiments were found to be in good agreement with the theoretical predictions. The main thrust of the project, however, was the development of an OPO based on urea as the non-linear medium and pumped at 308nm by the narrowband XeCl excimer laser. We were successful in constructing such an OPO, using an 8-mm-long, home-grown crystal, and were able to generate, continuously tunable output from 572 to 667nm, with a 2.5% energy conversion efficiency. The timing range of the device was later extended to 537-720nm, by utilising a 15-mm-long, home-grown urea sample, and its conversion efficiency was improved to as high as 37% at 90° phase-matching, with ≥ 10% efficiency over a 100-nm range in the visible (from 570 to 670nm). Finally, in an effort to achieve even higher efficiencies, we performed experiments in a 25-mm-long commercial urea crystal, and demonstrated exceptionally high external energy conversion efficiencies of up to 66%, with evidence of even higher levels of pump depletion (as high as 85%) at 90° phase-matching. The latter part of the project was concerned with the design and development of a similar device based on the new non-linear material, beta-BaB2O4, to provide continuously tunable radiation over a much broader tuning range, particularly in the blue and the near ultraviolet, not accessed by the urea OPO. We used a 12-mm-long commercially available beta-BaB2O4 crystal to construct this OPO, and successfully operated this device over the entire wavelength range from 354nm in the near ultraviolet, throughout the visible, to 2.37mum in the near infrared, with an energy conversion efficiency in excess of 10% over the range 450-960 nm. The constructed OPO's were also characterised with regard to several operating parameters, including oscillation threshold, spectral linewidth, as well as spatial and temporal variation and, where appropriate, the experimental results were compared with the predictions of theory.

Abstract:
A low threshold, efficient optical parametric oscillator (OPO) based on the material Potassium Titanyl Phosphate (KTP) and pumped by a diode-laser-pumped, Q-switched Nd:YLF laser has been demonstrated and investigated. This all-solid-state device was operated in a non-critical phase match (NCPM) geometry converting the 1 mum pump light to output wavelengths of 1.54 and 3.28 mum, and has potential as an 'eyesafe' laser source with scaling to higher powers. A major contributing factor to the success of this work was the extension of the steady state theory of the singly resonant OPO to include the build-up time effects that are dominant in the pulsed regime. A number of diode pumped lasers were constructed, allowing a comparison to be made between side- and end-pumping geometries, and also between the materials Nd:YAG and Nd:YLF. The end-pumping geometry in conjunction with the higher absorption and longer upper state lifetime in Nd:YLF made it the design of choice for the case of low pump pulse energies (~ 12 mJ at 797 nm). Anamorphic expansion of the laser mode in the plane parallel to the diode laser junction was employed to achieve TEM00 operation of this laser. Subsequent Q-switching with a polariser and LiNbO3 Pockels cell combination produced 2.2 mJ at 1.047 mum in an 18 ns pulse. Investigation of the dynamic loss of the Q-switch (which is due to the elasto-optic effect) allowed improvement of laser performance. The established model for a pulsed singly resonant OPO which describes the case for a plane-plane resonator was inappropriate in this work and so the steady state focused beam theory was extended to include time dependence. Fair agreement was found between the computer model and the experimental results, where the effects of pump and signal focusing, and output coupling were investigated. The high conversion efficiency of 30% for converting the 1 mum pump light to the eyesafe wavelength of 1.54 mum is superior to the present alternative source of the Er:glass laser. Pump energy thresholds of less than 0.5 mJ were obtained, along with internal conversions approaching 50 %. An empirical relation describing pump depletion was derived which showed good agreement with experiment. A high resolution investigation of the spectral properties of the OPO identified the roles of resonant reflection and doubly resonant behaviour on the mode structure of the output. The former suggests a way in which single mode operation could be achieved without the use of additional intracavity elements, or a seeding source.

Abstract:
The work described in this thesis is concerned with the development of self-modelocked Ti:sapphire lasers and femtosecond optical parametric oscillators based on periodically-poled rubidium titanyl arsenate and periodically-poled lithium niobate and operating in the near and mid-infrared. In Chapter 1 the theory of ultrashort pulse generation is explained with regard to the Ti:sapphire laser. The optical properties of Ti:sapphire are discussed along with the principles of laser oscillation and pulse generation. The techniques used to modelock the lasers used in the experimental work, which follows, are also considered. The second part of the chapter deals with typical measurement techniques for characterising femtosecond optical pulses from a laser or an OPO, including a detailed explanation of second harmonic generation autocorrelation. Chapter 1 concludes with a thorough description of frequency-resolved optical gating, the newest of these pulse characterisation techniques. In Chapter 2 the subject of nonlinear optics and the properties of nonlinear optical materials are discussed. Phasematching in nonlinear optical materials is explained along with the principle techniques for achieving this, including birefringent phasematching and quasi-phasematching. A review of techniques for periodically- poling nonlinear optical crystals is also given. The chapter concludes with a section on the optical effects of group velocity dispersion and self-phase modulation, that influence the output from an ultrashort pulse laser or OPO and describes methods for second and third-order dispersion compensation. Chapter 2 concludes the theory required to explain the experiments described in Chapters 3, 4, 5 and 6. Chapter 3 describes the operation and characterisation of two different Ti:sapphire laser systems involving different methods of dispersion compensation. The first laser produces 100 fs duration self-modelocked laser pulses and dispersion compensation is achieved by including a pair of prisms in the cavity. This laser system is discussed further in Chapter 5, where it is operated in conjunction with a Spectra Physics Millennia, as the pump source for an all-solid-state femtosecond OPO based on periodically-poled lithium niobate. A second laser system is described in Chapter 3, which produces self-modelocked pulses of ~15 fs duration and dispersion compensation is achieved by including chirped multilayer dielectric mirrors in the cavity. The subject matter that Chapter 4 is concerned with includes the operation and characterisation of a femtosecond OPO based on PPRTA. Ti:sapphire pump wavelength tuning and cavity-length tuning of the OPO are shown to produce wavelengths throughout the range 1.060 mum to 1.225 mum in the signal and 2.67 jam to 4.5 mum in the idler, with average output powers as high as 120 mW in the signal and 105 mW in the idler output. The effects of photorefractive damage are minimal and consequently this offers the possibility of room-temperature operation of the PPRTA- based OPO. Chapter 5 is concerned with the generation of longer idler wavelengths, in the region of 5 mum, from an all-solid-state OPO based on periodically-poled lithium niobate. The approach used with the PPRTA-based OPO is extended to PPLN and in Chapter 5, results are presented which show that the use of an all-solid-state Ti:sapphire pump source in combination with a PPLN-based OPO represents a robust source of high- repetition-rate femtosecond pulses in the mid-infrared at wavelengths out to ~5 mum. Significantly higher output powers in the signal and idler than previously reported are also measured. In Chapter 6 a similar PPLN-based OPO is described, with modifications to the cavity elements, to reduce the output pulse duration of the OPO. This system is pumped by a sub- 20 fs Ti:sapphire laser. A pulse duration of 175 fs is recorded for the signal at a wavelength of 1.07 mum. Output powers of 28 mW for the signal at 1.07 mum and 6.8 mW for the idler at 2.7 mum are also measured. The tuning range for the signal extends from 1.045 mum to 1.190 mum, and for the idler, extends from 2.57 mum to 3.67 mum.

Abstract:
The research presented in this thesis is concerned with the generation and characterisation of femtosecond pulses in the near and mid-infrared spectral regions. The three optical parametric oscillators which were constructed were synchronously- pumped by a self-modelocked femtosecond Ti:sapphire laser. Noncollinear critical birefringent phasematching was used in an oscillator based on KTiOAsO4, which was tunable from 1.03 to 1.2 mum and 2.51 to 4.1 mum by varying the crystal angle. The mid-infrared pulses were sub-100 fs, and essentially free from frequency chirp. With appropriate dispersion compensation the near-infrared signal pulses were temporally compressed to 69 fs. Theoretical models of noncollinear phasematching were derived and the results agreed closely with experiment. A novel optical parametric oscillator design based on a semi-monolithic noncritically phasematched RbTiOAsO4 crystal was implemented. This unique cavity configuration allowed independent focussing of the pump and signal beams within the crystal. It facilitated a reduction in cavity length to bring the signal pulse repetition rate into synchronism with the second (172 MHz) and fourth (344 MHz) harmonics of the pump pulse repetition frequency. Extraction efficiencies as high as 55% were observed. Quasi-phasematched femtosecond optical parametric oscillation was demonstrated in periodically poled lithium niobate. This device offered extensive tunability, covering 0.975 to 1.54 mum in the signal branch and 1.67 to 4.55 mum in the idler branch, from a combination of grating, pump wavelength and cavity length tuning. A theoretical model indicated that a very broad gain bandwidth allowed the wide tuning range. An attractively low oscillation threshold of 45 mW was recorded, and a visible output of 70 mW at 540 nm was observed, caused by simultaneously phasematched frequency-doubling of the signal output. The pulses from the Ti:sapphire laser and from the optical parametric oscillators were characterised by autocorrelation and frequency-resolved optical gating techniques. A highly advantageous autocorrelator arrangement based on quadratic nonlinearity in light-emitting diodes and photodiodes was demonstrated, and a novel second harmonic generation frequency-resolved optical gating system allowed real-time monitoring of pulsed outputs and complete characterisation of the intensity and phase of pulses.

Abstract:
High-repetition-rate femtosecond laser sources are essential laboratory tools for spectroscopy, microscopy, amongst other applications. With the relative length of one femtosecond to one second being similar to the length of 1 second compared to the age of the universe, such lasers enable scientists to probe physical processes at unimaginably short timescales. Furthermore, the high peak powers can excite strong nonlinear response in delicate material samples without delivering potentially damaging levels of energy. The infrared (IR) spectral region across 1–12 μmis rich in molecular absorption features, but in general poorly served by conventional coherent light sources. Optical parametric oscillators (OPOs) represent the most viable solution to this long-term issue, due to their table-top nature, and unparalleled tunability and spectral brightness in the near- and mid-IR. Recent breakthroughs in nonlinear crystal technology have opened the door to the generation of laser light in the previously difficult to access region above 4 μm, using high power lasers near 1 μm. Exploiting these new nonlinear materials to improve the spectral coverage and output power of OPOs has the potential to provide important societal benefits, particularly in the fields of frequency metrology, security, and medical imaging. In addition, theoretical modelling and exploration of devices with novel cavity designs can lead to technological advances which improve OPO affordability and increase their appeal to a wider scientific audience. In this thesis, we have demonstrated three OPOs across 1–8.4 μm in the infrared, which are pumped using well-established Ti:sapphire laser technology. The first is a compact and cost-effective device tunable across 1051–1700 nm in the near-IR, producing sub-100 fs pulses at 80 MHz. The incorportion of an optical fibre into the cavity leads to excellent passive power and wavelength stability, and enables soliton formation to be observed, together with other interesting nonlinear effects. We have also demonstrated an efficient, low-threshold mid-IR OPO exploiting group-velocity match effects in MgO:PPLN, which enables the use of a long (42 mm) nonlinear crystal. In doing so, we report quantum conversion efficiencies as high as 48% from the near-IR (s1 μm) pump to the mid-IR (3.1–4.3 μm), and use the source to perform basic spectroscopy. The third device uses Ti:sapphire light at s1 μm to directly pump the new nonlinear crystal, CdSiP2, generating up to 20 mW average power across 6.6–8.4 μm in the deep mid-IR. As the first demonstration of a single-stage Ti:sapphire-pumped deep mid-IR OPO with practical output powers, it has potential for medical imaging applications in the important amide II and III regions. Finally, upconversion imaging using femtosecond OPOs is reported and briefly discussed, together with future directions for deep mid-IR generation using orientationpatterned gallium phosphide (OP-GaP)
Las fuentes de láser de femtosegundo son instrumentos esenciales para espectroscopia, microscopía, entre otras aplicaciones. Dado que la duración relativa de un femtosegundo a un segundo es comparable con la duración de 1 segundo con respecto a la edad del universo, estos láseres permiten a los científicos investigar procesos físicos en escalas de tiempo increíblemente cortas. Además, las altas potencias de pico pueden provocar fuertes respuestas no lineales en materiales delicados sin entregar niveles de energía potencialmente dañinos. La región espectral del infrarrojo (IR) tiene numerosas características de absorción molecular, pero en general está mal servida por fuentes de luz coherentes convencionales. Los osciladores ópticos paramétricos (OPOs) representan la solución más viable para este problema a largo plazo, debido a su portabilidad, su capacidad de sintonizar y brillo espectral en el IR cercano y medio. Los avances recientes en la tecnología de cristales no lineales han permitido la generación de luz en la región de difícil acceso inferior a 4 μm, utilizando láseres de alta potencia cercanos a 1 μm. La explotación de estos nuevos materiales no lineales para mejorar la cobertura espectral y la potencia de salida de los OPOs, tiene el potencial de ofrecer beneficios sociales importantes, especialmente a través de los campos de metrología de frecuencias, seguridad e imágenes médicas. Además, el modelado teórico y la exploración de dispositivos con diseños de cavidades novedosos, puede conducir a avances tecnológicos que mejoran la asequibilidad del OPO y aumentan su atractivo para una audiencia científica más amplia. En esta tesis, hemos demostrado tres OPO en el rango espectral de 1–8.4 μm en el infrarrojo, que se bombean utilizando tecnología de làser bien establecida como el Ti: sapphire. En primer lugar, se demostró un dispositivo compacto y rentable, sintonizable a través de 1051–1700 nm en el IR cercano, que produce pulsos <100 fs a 80 MHz. La incorporación de una fibra óptica en la cavidad conduce a una excelente potencia pasiva y estabilidad de la longitud de onda, y permite observar la formación de solitones, con otros efectos no lineales interesantes. También hemos demostrado un OPO de infrarrojo medio eficiente, de bajo umbral, que explota la coincidencia de velocidad de grupo en MgO:PPLN, que permite el uso de un cristal no lineal largo (42 mm). Al hacerlo, reportamos eficiencias de conversión cuántica tan altas como 48% desde la bomba de IR cercano (~ 1 μm) hasta el IR medio (3.1–4.3 μm), y usamos la fuente para realizar la espectroscopia básica. El tercer dispositivo utiliza luz de láser Ti:sapphire cerca de 1 μm para bombear directamente el nuevo cristal no lineal CdSiP2, generando hasta 20 mW de potencia promedio con longitud de onda de 6.6–8.4 μm en el IR medio profundo. Como la primera demostración de un OPO de infrarrojo medio bombeado por un Ti:sapphire láser en una sola etapa con potencias de salida prácticas, tiene potencial para aplicaciones de imágenes médicas en las importantes regiones amida II y III. Finalmente, las imágenes de conversión ascendente que utilizan un OPO de femtosegundo es comentada y analizada brevemente, junto con los futuros avances para la generación de IR profundo con un cristal de OP-GaP.

Abstract:
A study of new materials for optical parametric oscillators (OPOs) was carried out using an XeCI excimer laser as a pump source. The three non-linear optical materials studied were lithium borate (LBO), deuterated L-arginine phosphate (d-LAP) and β-barium borate (BBO). These optical parametric oscillators were characterised for oscillation thresholds, tuning ranges, linewidths and efficiencies. A novel device in LBO was demonstrated, using the non-critically phase matched type II geometry. The device displayed a low oscillation threshold, which was independent of pump beam area thus made it attractive for use with low energy pump sources. The device was also shown to have a narrow inherent linewidth, oscillating on only one or two axial modes. Other geometries in LBO were also explored. The type I critical geometry displayed a very large tuning range covering the near ultra-violet, the visible and the near infra-red spectral regions. The type IT yz geometry was also studied. An OPO in d-LAP was demonstrated for the first time. The device was tunable in the blue/green spectral region and also in the near infra-red. A low threshold was observed for large beam sizes. Optically induced damage caused by the ultra-violet pump was also encountered. A comparison of the thresholds, efficiencies and tuning ranges of the three materials, LBO, d-LAP and BBO, was made and the suitability of each material for use in a line-narrowed oscillator discussed. Although possessing the largest linewidth, BBO was found to be the best suited due to its low oscillation threshold and large tunability. A single axial mode BBO OPO was demonstrated that was tunable from 385 nm to 560 nm and from 2300 nm to 684 nm. The line-narrowed OPO was then used for linewidth control of other devices. Firstly, an injection seeded OPO was demonstrated and the device was characterised for threshold and linewidth. Secondly, the line-narrowed OPO was used to seed an optical parametric amplifier (OPA). Single pass gains of ~20 were observed from the OPA.
