Abstract:
We report here an all-fiber structure tunable gas Raman laser based on deuterium-filled hollow-core photonic crystal fibers (HC-PCFs). An all-fiber gas cavity is fabricated by fusion splicing a 49 m high-pressure deuterium-filled HC-PCF with two solid-core single-mode fibers at both ends. When pumped with a pulsed fiber amplifier seeded by a tunable laser diode at 1.5 μm, Raman lasers ranging from 1643 nm to 1656 nm are generated. The maximum output power is ~1.2 W with a Raman conversion efficiency of ~45.6% inside the cavity. This work offers an alternative choice for all-fiber lasers operating at 1.6–1.7 μm band.

Abstract:
We demonstrated a compact tunable and switchable single/dual-wavelength erbium-doped fiber laser. The fiber laser can be tuned and switched from single-wavelength to dual-wavelength oscillation by using our recently proposed tunable comb filter. The comb filter consists of a section of multimode fiber (MMF) coiled into a polarization controller and two sections of single mode fibers (SMFs) to form a SMF/MMF/SMF structure, serving as a simple tunable all-fiber Mach-Zehnder interferometer. Due to the insertion of the MMF-based polarization controller (PC), an additional phase shift is introduced from the difference of the birefringence intensity in different dominant modes, which can be used to tune the fiber laser. In the experiment, by properly adjusting the PC, a tuning range of 9.3 nm can be achieved for the single-wavelength operation. Moreover, dual-wavelength operation with different free-spectral-ranges can be obtained. The tunable and switchable fiber lasers are of great importance for their applications in optical testing, optical fiber sensing, and signal processing.

Abstract:
We report here a high-power, highly efficient, wavelength-tunable nanosecond pulsed 1.7 μm fiber laser based on hydrogen-filled hollow-core photonic crystal fibers (HC-PCFs) by rotational stimulated Raman scattering. When a 9-meter-long HC-PCF filled with 30 bar hydrogen is pumped by a homemade tunable 1.5 μm pulsed fiber amplifier, the maximum average Stokes power of 3.3 W at 1705 nm is obtained with a slope efficiency of 84%, and the slope efficiency achieves the highest recorded value for 1.7 μm pulsed fiber lasers. When the pump pulse repetition frequency is 1.3 MHz with a pulse width of approximately 15 ns, the average output power is higher than 3 W over the whole wavelength tunable range from 1693 nm to 1705 nm, and the slope efficiency is higher than 80%. A steady-state theoretical model is used to achieve the maximum Stokes power in hydrogen-filled HC-PCFs, and the simulation results accord well with the experiments. This work presents a new opportunity for highly efficient tunable pulsed fiber lasers at the 1.7 μm band.

Abstract:
A tunable spacing dual-wavelength Q-switched fiber laser is experimentally demonstrated based on a fiber Bragg grating tunable device incorporated in an erbium-doped fiber laser (EDFL). The system utilizes two identical fiber Bragg gratings (FBGs) at 1547.1 nm origin to enable two laser lines operation. The wavelength separations between two laser lines are controlled by fixing one of the FBGs while applying mechanical stretch and compression to the other one, using a fiber Bragg grating tunable device. The seven steps of wavelength spacing could be tuned from 0.3344 to 0.0469 nm spacing. Pulse characteristics for both close and wide spacing of dual-wavelength Q-switched fiber laser are successfully being recorded. The findings demonstrate the latest idea of dual-wavelength fiber laser based on FBG tunable device, which offers a wide range of future applications.

Abstract:
Fiber lasers that operate at 1.7 μm have important applications in many fields, such as biological imaging, medical treatment, etc. Fiber gas Raman lasers (FGRLs) based on gas stimulated Raman scattering (SRS) in hollow-core photonic crystal fibers (HC-PCFs) provide an elegant way to realize efficient 1.7 μm fiber laser output. Here, we report the first all-fiber structure tunable pulsed 1.7 μm FGRLs by fusion splicing a hydrogen-filled HC-PCF with solid-core fibers. Pumping with a homemade tunable pulsed 1.5 μm fiber amplifier, efficient 1693~1705 nm Stokes waves are obtained by hydrogen molecules via SRS. The maximum average output Stokes power is 1.63 W with an inside optical–optical conversion efficiency of 58%. This work improves the compactness and stability of 1.7 μm FGRLs, which is of great significance to their applications.

Abstract:
Based on the simplified model of the tunable fiber laser system, the tuning performance of the laser was analyzed. Two kinds of tunable setups were established, which are the configurations with an external cavity and the configuration of the Littrow cavity. The tuning output characteristics experimentally were analyzed by means of setups. The simulation gives the output efficiency of two tunable lasers as 40% and 30%. In the experiment, the measured slope efficiency of the two lasers was 24% and 18.3%, and the tunable range of the two lasers was 32 nm and 40 nm, respectively. Both lasers could achieve laser output with good beam quality.

Abstract:
Linear tuning the frequency of an erbium-doped fiber ring laser using both a Fabry-Perot filter and an electro-optic tunable filter has been experimentally demonstrated. The rate of frequency change is determined by monitoring the fringes produced by laser light transmitted through a fiber Fabry-Perot interferometer. The fiber ring laser has been tuned over a 50 nm spectral range when using the Fabry-Perot filter and a tuning rate of 16480 nm/s has been achieved. The spectral width of the laser is 0.049 nm and the nearest sidelobe to the main peak is more than 30 dB below the central lobe. When the electro-optic tunable filter is used, a spectral range of 11 nm is reached. The spectral width is 2.33 nm and is in close agreement with the filter theoretical results. The sidelobe to main peak difference is around 13 dB.

Les travaux de recherche, rapportés dans ce manuscrit, portent sur l’étude d’un laser à fibre en forme de huit et le développement de sources à 1.6 µm. En premier temps, nous avons étudié la dynamique impulsionnelle d’un laser à fibre micro-structurée en forme de huit. L’objectif est de montrer l’impact des propriétés de la fibre micro-structurée sur le comportement impulsionnel du laser. Nous avons également étudié le phénomène d’hystérésis dans cette cavité. Nos résultats numériques ont permis de démontrer l’universalité de ce phénomène dans les cavités lasers. Autrement, il est indépendant de la technique de verrouillage de modes. En second lieu, nous avons développé une source laser émettant à 1.6 µm à partir d’un amplificateur fonctionnant dans la bande C. La méthode que nous avons explorée est basée sur la gestion des pertes linéaires. L’émission, en continu et en verrouillage de modes, a été démontrée dans deux configurations différentes. Enfin et en se basant sur ce concept, nous avons rapporté des sources accordables sur une large fenêtre spectrale. Nous avons également étudié différentes formes des régimes harmoniques autour de 1.6 µm
During our research, we are interested in studying of the figure of eight fiber laser based on the microstructured optical fiber and developing a 1.61 µm mode locked fiber laser from a C-band double-clad Er : Yb doped fiber amplifier. In the first step and based on a theoretical model, we have investigated the multi-pulse emission of a microstructured figure-of eight fiber laser operating in passive mode-locking. The proposed laser is mode locked by the nonlinear amplifying loop mirror (NALM). We further study the hysteresis dependence and the number of pulses in steady state as a function of both the small signal gain and the nonlinear coefficient of microstructured fiber. Our results demonstrate that the nonlinear coefficient of microstructured fiber plays a key role in the formation of multi-soliton. In the second step and based on the control of the linear losses of the cavity, we demonstrate the possibility to achieve filter less laser emission above 1.6 μm, from a C-band double-clad Er: Yb doped fiber amplifier, using a figure-of-eight geometry and a unidirectional ring cavity. We also reported a widely tunable mode locked fiber laser and harmonic mode locking of twin and third pulse around 1.61 µm

Abstract:
High-power, continuous-wave (cw), mid-infrared (mid-IR) laser sources are of interest for variety of applications such as trace gas detection and remote sensing, which require broad spectral coverage to address the most prominent absorption features of a wide range of molecular species particularly in the mid-IR fingerprint region. On the other hand, surgical applications require high energy sources with unique pulse structure at specific wavelength in the mid-IR ranging from 6-6.5 m. Optical parametric oscillators (OPOs) offer potential sources for all the above applications. The output wavelengths of a singly-resonant oscillator (SRO) can be coarsely tuned over wide ranges through the adjustment of the nonlinear crystal temperature, phase-matching angle or, in the case of quasi-phase-matched (QPM) the first time. The high-energy CSP OPO marked the first demonstration of a compact, high-repetition-rate OPO synchronously pumped by a master oscillator power amplifier system at 1064 nm, generating an milli-joule pulses in the 6-6.5 m spectral range, which is technologically important for surgical applications. Additionally, we also demonstrated a fiber-based-green source at 532 nm, based on single-pass second harmonic generation (SHG) in MgO:sPPLT, as an alternative pump source for Ti:sapphire laser, pointing towards the future, compact fiber-laser pumped Ti:sapphire lasers. Further efforts to improve the SHG efficiency led to the development of a novel multi-crystal scheme, enabling single-pass SHG efficiency as high as 56%. This generic technique is simple and can be implemented at any wavelength. materials, the QPM grating period. The combination of SRO with a tunable pump laser allows the development of uniquely flexible and rapidly tunable class of mid-IR sources. In this thesis we have demonstrated several mid-IR OPOs in the cw as well as ultrafast picosecond regime pumped by fiber-lasers making them compact and robust. In the cw regime, we developed a high-power, Yb-fiber-laser pumped mid-IR OPO based on MgO:PPLN spanning 1506-1945 nm in the near-IR and 2304-3615 nm wavelength range in the mid-IR, efficiently addressing the thermal effects by implementing the optimum signal output coupling. Novel materials such a MgO:sPPLT, with better optical and thermal properties for cw mid-IR generation are explored. High-power broadband, cw mid-IR generation is also demonstrated by using the extended phase-matching properties of MgO:PPLN. Further, we also demonstrated a simple, inexpensive and novel interferometric technique for absolute optimization of output power from a ring optical oscillator. We deployed a picosecond Yb-fiber-laser pumped mid-IR OPO based on MgO:PPLN in ring cavity configuration to demonstrate this proof-of-principle experiment for
Fuentes coherentes de luz continua y de alta potencia en el infrarrojo-medio (mid-IR) son de gran interés por su aplicación en la detección de gases, detección remota y la observación de imágenes. Estas aplicaciones requieren un ancho de banda amplio para evidenciar las características que ofrece la absorción de una gran variedad de especies moleculares, particularmente en la región “finger print” del mid-IR. Por otra parte, fuentes altamente energéticas con pulsos que posean estructuras peculiares en rangos específicos de longitud de onda en el mid-IR, entre 6-6.5 m. , prometen características únicas para nuevas aplicaciones en cirugía. Osciladores ópticos paramétricos (OPOs) constituyen fuentes de luz versátiles y apropiadas para todas las aplicaciones mencionadas anteriormente. La longitud de En el régimen ultrarápido, hemos demostrado una nueva técnica de interferometría para la optimización absoluta de la potencia de salida de un oscilador óptico con una cavidad de anillo. Como demostración de principio, implementamos, por primera vez, un OPO de picosegundos en el mid-IR basado en MgO:PPLN con una cavidad de anillo bombeado por un láser de fibra de Yb. Además, hemos desarrollado un nuevo OPO de alta energía en el mid-IR basado en el material nolineal CSP. Esto representa la primera demostración de un OPO compacto de alta repetición sincrónicamente bombeado por un láser de estado sólido a 1064 nm generando pulsos de milijulios en el rango espectral 6-6.5 m. Esta radiación es importante para aplicaciones en cirugía. Adicionalmente, hemos demostrado una fuente verde, 532 nm, basada en láseres de fibra. Esta radiación se obtiene por medio de la generación de segundo harmónico (SHG) en un paso individual en MgO:sPPLT. Esto representa una nueva alternativa de bombeo para los láseres de Ti:sapphire que los harán compactos en el futuro. Los esfuerzos para mejorar la eficiencia de segundo harmónico resultaron en el desarrollo de un novedoso esquema que utiliza múltiples cristales y permite eficiencias de SHG de paso individual del 56%. Este esquema es general y simple y puede ser implementado para cualquier longitud de onda. onda de un OPO puede ser sintonizada en regiones amplias del espectro cambiando la temperatura del cristal no-lineal, el ángulo de ajuste de fase o, al considerar materiales cuasi ajuste de fase (QPM), cambiando el periodo de red. En esta tesis, hemos demostrado una gran variedad de OPOs en el mid-IR en régimen continuo y de pulsos de picosegundo. Estos OPOs han sido bombeados por láseres de fibra permitiendo un diseño compacto y resistente. En el régimen de emisión continua, hemos implementado un OPO de alta potencia basado en MgO:PPLN bombeado por un láser de fibra. Este OPO es sintonízable en el rango 1506-1945 nm correspondiente al infrarrojo-cercano y en el rango 2304-3615 nm correspondiente al mid-IR. Esta capacidad de sintonización se logra al sobrepasar eficientemente los efectos térmicos optimizando el acoplamiento de salida. Materiales nuevos como el MgO:sPPLT, con propiedades ópticas y térmicas mejoradas para la generación de radiación continua en el mid-IR han sido estudiados. Utilizando las propiedades ajuste de la fase extendió del MgO:sPPLT, fuentes continuas de alta potencia con un gran ancho de banda en el infrarrojo-medio también han sido implementadas.

Abstract:
Dans le cadre d’un projet collaboratif entre le laboratoire XLIM (UMR 7252 du CNRS et de l'Université de Limoges) et le laboratoire de recherche IPHT situé à Jena en Allemagne, mon projet de thèse consiste à développer un laser à fibre dopée thulium bi-fréquences largement accordable à impulsions synchrones pour la réalisation d’une source Térahertz puissante et accordable. Basé sur l’utilisation de deux réseaux de Bragg en volume (VBGs) et d’une fibre dopée thulium à double gaine et à maintien de polarisation (diamètre de coeur = 20 μm) fabriquée par la méthode REPUSIL, un laser mono-fréquence et bi-fréquences largement accordable a été réalisé et étudié en régime continu. Une accordabilité de 1nm à 144 nm a été obtenue avec une puissance supérieure à 4,5 W et un bon contraste signal sur bruit (~45 dB) et une largeur spectrale inférieure à 0,1 nm. En régime déclenché, un modulateur acousto-optique (AOM) a été utilisée en espace libre dans la cavité laser afin de générer les impulsions. La fibre à double gaine a été remplacée par une fibre dopée thulium à large coeur (40 μm) appelée FA-LPF pour repousser le seuil d’apparition des effets non-linéaires et travailler avec une fibre courte pour diminuer la durée d’impulsion et augmenter la puissance crête des impulsions obtenues. Une source déclenchée bi-fréquences largement accordable (de 3,8 nm jusqu’à 120nm) a été développée avec une puissance crête supérieure à 8 kW et une durée d’impulsion autour de 26 ns obtenues indépendamment de la valeur de Δλ pour une fréquence de répétition de 1 kHz. Un contraste supérieur à 20 dB a été obtenu limité par les pics parasites générés par le FWM pour les valeurs de Δλ inférieures à 45 nm. La largeur spectrale des raies lasers mesurée à 3 dB du maximum a été inférieure à 0,3 nm
As part of a collaborative project between the XLIM laboratory (UMR 7252 of the CNRS and the University of Limoges) and the IPHT research laboratory located in Jena, Germany, my thesis project consists in the development of a widely tunable dual-wavelength synchronous pulsed thulium doped fiber laser for the realization of an efficient and tunable terahertz source. Based on the use of two volume Bragg gratings (VBGs) and a double-clad, polarization-maintaining thulium doped fiber (core diameter = 20 μm) manufactured by the REPUSIL method, a widely tunable single-wavelength laser and dual-wavelength laser has been realized and studied in continuous regime. A tunability of 1 nm to 144 nm was obtained with a power more than 4.5 W and a good signal-to-noise contrast (~ 45 dB) and a spectral linewidth less than 0.1 nm. In pulse regime, an acousto-optic modulator (AOM) was used in free space in the laser cavity to generate the pulses. The double-clad fiber has been replaced by a large-core thulium doped fiber (40 μm) called FA-LPF to to fend off the threshold of non-linear effects and work with a short fiber to decrease the pulse duration and increase the peak power of the obtained pulses. A widely tunable (from 3.8 nm to 120 nm) Q-switched dual-wavelength synchronous-pulsed thulium-doped fiber laser was developed with a peak power more than 8 kW and a pulse duration around 26 ns obtained independently of the value of Δλ at 1 kHz of repetition rate. A contrast higher than 20 dB was obtained limited by the FWM peaks generated for Δλ values below 45 nm. The spectral linewidth of the laser measured at 3 dB of the maximum was less than 0.3 nm

Abstract:
Neste trabalho, descreve-se a geração de pulsos ópticos curtos com diferentes taxas de repetição, para aplicações em sistemas de transmissão de sólitons. Para isto foi desenvolvido um laser a fibra em anel operando na terceira janela de comunicações ópticas (em 1.55 mm), capaz de gerar pulsos curtos, utilizando a técnica de mode-locking ativo. Na configuração empregada o modulador de Mach- Zehnder, normalmente usado, foi substituído por um laser DFB, funcionando como modulador de intensidade e, ao mesmo tempo, como filtro óptico sintonizável. O laser semicondutor tem seu ganho chaveado através de modulação direta, levando a cavidade e operar no regime de mode- locking harmônico. Uma sintonia contínua de comprimentos de onda pode ser obtida, simplesmente, variando-se a temperatura do diodo laser. Foram analisados aspectos como estabilidade, duração e pureza espectral dos pulsos ópticos emitidos por essa fonte, bem como sua faixa de sintonia de comprimentos de onda e possíveis taxas de repetição. Os pulsos ópticos gerados foram transmitidos através de enlaces ópticos com fibra óptica convencional, comprovando-se a propagação de sólitons.
In this dissertation, it is depicted short optical pulses generation with different repetition rates, for soliton based transmission systems applications. In order to accomplish that, a fiber laser operating at the third window of the optical communication (1.55 um) was developed, capable of generate short pulses, through the active mode-locking technique. Within the current configuration, the Mach-Zehnder modulator, usually employed, was replaced by a DFB laser, running as both an intensity modulator and tunable optical filter. The semiconductor laser was gain switched through direct modulation, leading the cavity to operate on harmonic mode- locking scheme. A continuous wavelength tuning could be achieved by changing the temperature of the diode laser. Several aspects were analyzed, such as stability, duration and spectral purity of the optical pulses generated by this source. The wavelength tuning range and its possible repetition rates were also investigated. The optical pulses were transmitted through standard optical fiber links, demonstrating the propagation of solitons.
