Abstract:
Abstract The problem of small bit error rate is actual in fiber Raman amplifiers. Our experimental data on the amplified spontaneous emission (ASE) with backward pumping as a base of optical noise evaluation are presented in this paper. Raman gain spectrum for useful Stokes low-powered signal is calculated and compared with obtained spectrum of non-coherent ASE noise. It is shown that output optical signal has better gain than the amplified spontaneous emission that leads to appreciable growth of output optical signal-to-noise ratio.

AbstractThe minimum irradiance needed to overcome amplified spontaneous emission (ASE) of a seed beam injected into a laser amplifier is evaluated. The treatment is particularly applicable to extreme ultraviolet (EUV) and X-ray laser schemes to inject laser harmonic radiation as a seed into (1) plasma laser amplifiers and (2) free-electron lasers. Simple expressions and calculations are given for the minimum injected irradiance required for amplification of the injected seed beam to exceed ASE from the amplifier, including the effects of gain saturation, assuming one dimensional radiative transfer.

Abstract:
Abstract In this paper, the effects of pump pulse fluence on the output energy and amplified spontaneous emission (ASE) of a femtosecond regenerative amplifier are investigated. One can easily enhance the output energy of laser amplifiers by increasing their pump fluence. This in turn can increase the ASE and reduce the performance of amplifiers in terms of output beam quality, beam stability, etc. This effect would eventually lead to what is called ‘temporal intensity contrast deterioration’. In this work, it is shown that an optimum state of the pump pulse fluence can indeed optimize the amount of the output energy from a regenerative amplifier without much reducing the performance of the amplifier due to the higher ASE. Temporal gain characteristics were employed to achieve this optimum value for a better design, performance, and maintenance of femtosecond laser amplifiers. The results of the current study can be effectively used in designing a wide range of regenerative amplifiers for femtosecond pulses.

Abstract:
Reversible oxygen induced emission quenching of both the Spontaneous Emission (SE) and the Amplified Spontaneous Emission (ASE) of poly(9,9-dioctylfluorene) waveguides is demonstrated. We show that ASE shows a stronger quenching than SE, up to about 6.2 times, but also a stronger decrease when the excitation density increases. We conclude that the fast increase of the ASE decay rate is the main process in determining the ASE detection sensitivity, limiting the potentiality of sensitivity improvement of ASE with respect to SE.

Abstract:
AbstractIn order to achieve the truncated amplified spontaneous emission pulse, the method of timeshare quenching was proposed in this paper. When the original pulse of the amplified spontaneous emission is 16.72 ns, the obtained best results show that the pulse width is truncated to 2.48 ns, and the shortening ratio is approximately 6.7. By analyzing the 12 acquisition results of the continuous amplified spontaneous emission truncation, 2.59 ± 0.05 ns amplified spontaneous emission pulse was obtained. The experimental results showed that the stability of the truncated pulse width is well. This method is applicable to truncate the ASE pulse in KrF excimer laser. It is significantly to the research of the inertial confinement fusion.

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Chemistry, 2002.
Includes bibliographical references.
This thesis details efforts in using cadmium selenide (CdSe) nanocrystallites (NCs) as a novel lasing media. We begin with the synthesis of polymer/NC composites, in which the NCs are stabilized within a long-chain methacrylate polymer. This chapter serves to highlight the processing flexibility afforded by the NCs as well as some of the salient linear optical properties of NCs. The wide range of colors that are accessible using these NCs and the ability to excite them simultaneously are emphasized and provide an incentive to use them as a gain medium. Chapter 3 summarizes work done in developing a NC-based gain media and lists the stringent requirements for observing amplified spontaneous emission (ASE), a signature manifestation of gain. Then the synthesis of a robust NCs-titania, sol-gel matrix is described which satisfies these requirements. We exploit the stability and processability of these matrices to study the optical properties of the NC gain media.
(cont.) True temperature independent gain and ASE thresholds are shown to present, thus confirming early theoretical predictions of strongly-confined, zero dimensional gain media. Chapter 4 considers the incorporation of such structures with a suitable feedback structure and presents evidence for the first NC based distributed feedback laser. Room-temperature operation of such devices is shown to follow naturally from the unique gain features of the constituent NCs. Chapter 5 emphasizes the flexibility inherent in using these NCs as a gain media. We combine the processability of NC-titania films with soft-lithographic techniques to construct more complicated lasing structures. Simultaneous, mixed-colored lasing is shown to be possible, which might allow for new devices that operate within a wide gain window.

Abstract:
Surface plasmon-polaritons are optical surface waves formed through the interaction of photons with free electrons at the surface of metals. They offer interesting applications in a broad range of scientific fields such as physics, chemistry, biology, and material science. However, many of such applications face limitations imposed by the high propagation losses of these waves at visible and near-infrared wavelengths, which result mainly from power dissipation in the metal. In principle, the propagation losses of surface plasmon-polaritons can be compensated through optical amplification. The objective of this thesis is to provide deeper insights on the physics of surface plasmon-polariton amplification and spontaneous emission in surface plasmon-polariton amplifiers through theoretical and experimental vehicles applied (but not necessarily restricted) to a particular plasmonic mode termed long-range surface plasmon-polariton. On the theoretical side, the objective is approached by developing a realistic theoretical model to describe the small-signal amplification of surface plasmon-polaritons in planar structures incorporating dipolar gain media such as organic dye molecules, rare-earth ions, and quantum dots. This model takes into account the inhomogeneous gain distribution formed near the metal surface due to a non-uniform excitation of dipoles and due to a position-dependent excited-state dipole lifetime that results from near-field interactions between the excited dipoles and the metal. Also, a theoretical model to describe the amplified spontaneous emission of surface plasmon-polaritons supported by planar metallic structures is developed. This model takes into account the different energy decay channels into which an exited dipole located in the vicinity of the metal can relax. The validity of this model is confirmed through experimentation. On the experimental side, the objective is approached by providing a direct experimental demonstration of complete loss compensation in a plasmonic waveguide. The experiments are conducted using the long-range surface plasmon-polariton supported by a symmetric thin gold waveguide incorporating optically pumped organic dye molecules in solution as the gain medium. Also, an experimental study of spontaneous emission in a long-range surface plasmon-polariton amplifier is presented. It is shown that this amplifier benefits from a low spontaneous emission into the amplified mode, which leads to an optical amplifier with low noise characteristics. The experimental setup and techniques are explained in detail.

Abstract:
On trouve sur la plateforme de thèses en ligne Pastel le résumé suivant : Le développement du laser a ouvert la voix à l'exploration de nouveaux domaines scientifiques et industriels. Les impulsions laser à haute intensité sont un outil unique pour les études d'interaction lumière/matière et leurs applications. Mais elles sont générées par des systèmes laser reposant sur l'utilisation de milieux à gain en verre pompés par des lampes flashes et sont donc intrinsèquement limitées en termes de cadence et d'efficacité. Le développement, au cours de ces dernières années, des lasers semi-conducteurs a attiré l'attention sur une nouvelle classe de lasers, les « laser solides pompés par diodes » (DPSSL). Ils possèdent une grande efficacité et sont des candidats de choix pour les systèmes compacts à haute puissance moyenne requis pour des applications industrielles, mais aussi en tant que sources de pompe à haute puissance pour des lasers ultra-intenses. Les travaux décrits dans cette thèse s'inscrivent dans le cadre du système laser Lucia (1 kilowatt de puissance moyenne), actuellement en construction au «Laboratoire d'Utilisation des Intenses lasers» (LULI) à l'Ecole Polytechnique, France. La génération d'impulsions laser de durée sub-10 nanosecondes avec des énergies allant jusqu'à 100 joules et des taux de répétition de 10 hertz est principalement limitée par l'émission spontanée amplifiée (ASE) et les effets thermiques. L'étude de ces limitations est le thème central de ce travail. Leur impact est discuté dans le cadre d'un premier jalon énergétique fixé vers 10 joules. Le système laser mis au point est présenté en détails depuis l'oscillateur jusqu'à la fin de la chaine d'amplification. Une discussion complète de l'impact de l'ASE et des effets thermiques est complétée par des vérifications expérimentales. Les modèles de simulation informatique développés sont validés puis utilisés pour prédire les performances du système laser qui, lors d'une première activation, à atteint un niveau d'énergie de 7 joules en régime mono-coup et de 6,6 joules pour un taux de répétition de 2 hertz. Les limitations actuelles sont discutées ainsi que les approches envisagées pour des développements futurs
On trouve sur la plateforme de thèses en ligne Pastel le résumé suivant : The development of the laser triggered the birth of numerous fields in both scientific and industrial domains. High intensity laser pulses are a unique tool for light/matter interaction studies and applications. However, current flash-pumped glass-based systems are inherently limited in repetition-rate and efficiency. Development within recent years in the field of semiconductor lasers and gain media drew special attention to a new class of lasers, the so-called Diode Pumped Solid State Laser (DPSSL). DPSSLs are highly efficient lasers and are candidates of choice for compact, high average-power systems required for industrial applications but also as high-power pump sources for ultra-high intense lasers. The work described in this thesis takes place in the context of the 1 kilowatt average-power DPSSL program Lucia, currently under construction at the ‘Laboratoire d'Utilisation des Laser Intenses' (LULI) at the Ecole Polytechnique, France. Generation of sub-10 nanosecond long pulses with energies of up to 100 joules at repetition rates of 10 hertz are mainly limited by Amplified Spontaneous Emission (ASE) and thermal effects. These limitations are the central themes of this work. Their impact is discussed within the context of a first Lucia milestone, set around 10 joules. The developed laser system is shown in detail from the oscillator level to the end of the amplification line. A comprehensive discussion of the impact of ASE and thermal effects is completed by related experimental benchmarks. The validated models are used to predict the performances of the laser system, finally resulting in a first activation of the laser system at an energy level of 7 joules in a single-shot regime and 6. 6 joules at repetition rates up to 2 hertz. Limitations and further scaling approaches are discussed, followed by an outlook for the further development

Abstract:
This book is an introduction to quantum optics for students who have studied electromagnetism and quantum mechanics at an advanced undergraduate or graduate level. It provides detailed expositions of theory with emphasis on general physical principles. Foundational topics in classical and quantum electrodynamics, including the semiclassical theory of atom-field interactions, the quantization of the electromagnetic field in dispersive and dissipative media, uncertainty relations, and spontaneous emission, are addressed in the first half of the book. The second half begins with a chapter on the Jaynes-Cummings model, dressed states, and some distinctly quantum-mechanical features of atom-field interactions, and includes discussion of entanglement, the no-cloning theorem, von Neumann’s proof concerning hidden variable theories, Bell’s theorem, and tests of Bell inequalities. The last two chapters focus on quantum fluctuations and fluctuation-dissipation relations, beginning with Brownian motion, the Fokker-Planck equation, and classical and quantum Langevin equations. Detailed calculations are presented for the laser linewidth, spontaneous emission noise, photon statistics of linear amplifiers and attenuators, and other phenomena. Van der Waals interactions, Casimir forces, the Lifshitz theory of molecular forces between macroscopic media, and the many-body theory of such forces based on dyadic Green functions are analyzed from the perspective of Langevin noise, vacuum field fluctuations, and zero-point energy. There are numerous historical sidelights throughout the book, and approximately seventy exercises.

Abstract:
Recently the time dependence of gain in a Ti:Al2O3 amplifier was measured.1 It was shown that the decay of gain was much more rapid than expected if only spontaneous decay was responsible for depletion of the upper state. Although it was believed that amplified spontaneous emission (ASE) might be responsible for this difference, the apparent difficulty of calculating the effect of ASE inhibited pursuit of this conjecture. A rate equation has been used to demonstrate that ASE can quantitatively explain the fast decay. In this model, the gain of the amplifier is e γ , where γ obeys the time-dependent spatially integrated equation The three terms on the right-hand side of this equation describe the spontaneous emission rate, pump rate, and stimulated emission rate caused by the input to the amplifier and by ASE, respectively. Excellent fits of the experimental data have been obtained using only one parameter Ω, the effective solid angle for ASE. The fitted parameter is in good agreement with geometrical estimates.

Abstract:
Recently, Lee and Hahn1 demonstrated high energy efficiency of a four-pass amplifier by passing the laser beam back and forth four times on a single axis through a gain medium. This four-pass amplifier was capable to suppress self-oscillation to be generated by the laser beam traveling through the same pass in a high gain medium. However, the output beam of the four-pass amplifier involves quite big amplified spontaneous emission(ASE). They reported that the ASE portion reached to 15 % in normal operation. In the present work we introduce a new design of a four-pass amplifier suppressing the generation of ASE during the amplifying process, and describe the detailed operational characteristics of the new four-pass amplifier.

Abstract:
We report new observations of a fast fluorescence process on 6p—6s transitions in xenon (0.01-5 Torr). A 600-ps pulse (λ~ 250 nm, Δν~ 3 GHz) from a frequency-doubled dye laser populates a single 6p state by two-photon coupling. The ensuing fluorescence (823 nm < λ < 993 nm) is collected by f/1 optics, detected by a photomultiplier or microchannel plate phototube, and displayed on an oscilloscope (1-GHz bandwidth) or digitized and recorded for statistical analysis. We previously characterized the emission process as amplified spontaneous emission (ASE) based on emission rate (> 10× spontaneous), high directionality, existence of threshold, and other time-independent characteristics.1 New time-resolved observations with the microchannel plate detector (500-ps overall rise time) showed that far above threshold the fluorescence pulses temporally reproduced the excitation pulses and occurred simultaneously. Pulses near threshold showed widths up to 3 ns and delays up to 3.5 ns. Ringing or multiple-pulse emission also occurred. When the emission was spontaneous, fluorescence energy yields showed the quadratic dependence expected of two-photon excitation and decreased monotonically when N2 was added to the xenon. ASE-dominated yields were linear in excitation energy and increased when N2 was introduced. ASE yields were smaller than predictions based on work of Raymond et al. 2 Mechanisms for these results are discussed.
