Resumen
The purpose of this work is determines of formation patterns of opti- cal ceramics Mg2+,Cr4+:YAG and Ca2+,Cr4+:YAG as model objects promising for use as a passive Q-switch. Optical ceramics Ca2+,Cr4+:YAG and Mg2+,Cr4+:YAG was synthesized by solid-phase reaction sintering in vacuum. The influence of calcium, magnesium and chromium ion concentrations on the structure and the optical properties of ceramics Mg2+,Cr4+:YAG have been investigated. The optimized chromium concentration 0.5 at. % allows to obtain Mg2+,Cr3+:YAG ceramics with optical transmission of about 81 % at λ = 1064 nm after vacuum sintering and the absorption coefficient of about 1.4 cm–1 after air annealing. The optimized calcium concentration 0.5 at. % allows to obtain Са2+,Cr3+:YAG ceramics with an optical transmission of about 80 % at λ = 1064 nm after vacuum sintering and the absorption coefficient of about 2.4 cm–1 after air annealing.

Resumen
Commercial Y2O3 powders were subjected to high energy ball milling in a planetary ball mill using high purity alumina balls and vial. The refined Y2O3 power ,with commercial high-purity Al2O3, Cr2O3 and Yb2O3 powders, were used as raw materials. Transparent ytterbium and chromium codoped yttrium aluminum garnet (Yb,Cr:YAG) ceramics were fabricated by a solid-state reaction method. The Yb,Cr:YAG ceramics exhibit a pore free structure and the average grain size is about 10 micron. The strong absorptions at 940 and 968 nm of Yb3+ are suitable for InGaAs diode laser pumping, and there is an absorption band at 1030 nm, which is suitable for passive Q-switch laser output at 1030 nm. Transparent Yb,Cr:YAG ceramics may be a potential material for compact, efficient, high-stability diode-laser-pumped passive Q-switched solid-state lasers.

Resumen
Parmi les nombreuses applications des sources laser, certaines nécessitent une propagation du faisceau dans l'atmosphère sur plusieurs kilomètres : télémétrie, désignation, ou encore imagerie active. Pour éviter tout risque oculaire tout en proposant de plus grandes portées, ces applications doivent faire appel à des sources laser émettant une longueur d'onde dans la gamme à sécurité oculaire autour d'un minimum local d'absorption de l'atmosphère (1550-1650 nm). De telles sources existent déjà commercialement, mais ne répondent pas aux exigences militaires de compacité, de consommation électrique, de performance et de fonctionnement sur une large gamme de température (-40°C/+60°C).Mes travaux de thèse tentent d'apporter une réponse à l'ensemble de ces exigences. Avec l'aide des partenaires industriels Fibercryst et Cilas, ils portent sur la réalisation de sources laser compactes et efficaces à fibre cristalline Er3+:YAG directement pompée par une diode laser pour des applications militaires.A l'aide d'un algorithme de simulation d'un laser Er3+:YAG déclenché passivement élaboré et affiné durant la thèse, plusieurs sources sont réalisées expérimentalement. L'étude autour des absorbants saturables pour le déclenchement passif a permis une amélioration notable des caractéristiques du faisceau.Ces recherches, dont les résultats peuvent déjà présenter un certain intérêt commercial, ouvrent la voie vers de nouvelles techniques et architectures autour des sources laser à cristaux dopés aux ions erbium pour la conception de futurs prototypes plus performants
Among the several applications of laser sources, some requires kilometers range propagation in the atmosphere : telemetry, guidance system or active imagery. High pulse energy improves the range of the system, but may cause permanent blindness to an observer's eyes. Hence, these applications must use laser beam which wavelength are located in the eye-safe region, ideally at the local minimum of the atmosphere absorption (1550-1650 nm). Such laser sources are already commercially available, but are not suited for the demanding military needs : compacity, electrical consumption, performance and large operating temperature range (-40°C/+60°C).My work aims to develop a laser source filling these specifications. Thanks to the collaboration with the industrial partners Fibercryst and Cilas, it focuses on the design of a compact, efficient, directly diode-pumped Er3+:YAG single cristal fiber laser for military applications.With a homemade numerical simulation of a passively Q-switched Er3+:YAG laser source, many laser emitters are experimentally designed and compared. Further studies around saturable absorbers allowed sensible improvements of the output pulse energy.This work, whose results may already be commercially interesting, may lead to new technics and architectures of erbium doped solid-state laser for better prototypes

Resumen
This thesis studies the relationship between the pairs of resonator output coupling and intra-cavity absorber initial transmission, and the FWHM (full width at half maximum) pulse duration of a continuously pumped passively Q-switched solidstate laser, when the output energy is pre-determined. Depending on the magnitude of the pumping power, three different rate equation models are used to evaluate the required output coupler reflectivity and absorber initial-transmission pair for the corresponding FWHM pulse duration. The energy transfer kinetics of the passively Q-switched laser decides the required pumping power; and the pair of output coupler reflectivity absorber transmission pair, determine the build-up time of Q-switching and the repetition rate of the laser system. Hence, the forms of the models are controlled by two conditions: 1) the build-up time of Q-switching; and 2) the recovery time of the absorber. When the build-up time of Q-switching is relatively short, but the recovery time of the absorber is long, Model I is based on the simplified laser rate equations. It is used to evaluate the output coupler reflectivity and absorber initialtransmission pair, which satisfies the pre-determined output energy and FWHM pulse duration. Model II is set up to study the case when both the build-up time of Q-switching and the recovery time of the absorber are long. In Model II, the laser rate equations are solved using the Runge-Kutta method. Model III simulates the case when the recovery time of the absorber is short. To validate the models, the simulation results of practical passively Q-switched laser systems are compared with experimental results reported in the literature. The agreement of the simulation results with reported experimental results demonstrates the importance of the boundary conditions for the different cases, and verifies the soundness of the models. Generalizing the simulation results, obtained from different passively Q-switched laser systems with different pumping power and different pre-determined output energy, yields general conclusions which permit a designer to select the correct parameters for a desired laser performance.

This work deals with the characterization of compact solid state lasers, as a first approach to the study of the microchip laser concept applied to several rare earth-doped crystalline hosts. The results on the study of the thermal lens, required for the microchip laser operation as well as the continuous wave and passive Q-switched laser operation in microchip configuration are reported. In the experiments, the microchip concept is defined as a quasi-monolithic laser cavity. Such a concept is studied for different laser emissions at ~1.06 μm from Yb3+ and Nd3+ ions, at ~1.3 μm from Nd3+, at ~1.95 μm from Tm3+ and at ~2.05 μm from Ho3+. The continuous wave regime is examined in detail for the above mentioned trivalent lanthanide ions embedded in several crystalline hosts with the aim to compare the potential of each gain material. Slope efficiencies very close to the theoretical limit are demonstrated in this work. On the other hand, microchip solid state lasers passively Q-switched with several saturable absorbers are also presented. For this purpose, novel nanomaterials such as MoS2, carbon nanostructures (SWCNTs, single- and multilayer graphene) and a SESA are used as saturable absorbers. Besides, the most conventional Cr:YAG (~1.06 μm) and Cr:ZnS (~1.9 μm) are examined to compare their performance.

Resumen
El doble tungstato cristalino de potasio y lutecio con estructura monoclínica, KLu(WO4)2, se ha establecido como una nueva matriz laser de estado sólido para iones de Tm, Yb y Ho debido a (i) las altas secciones eficaces de absorción y emisión; (ii) la relativamente larga distancia entre iones Lu-Lu permitiendo altos niveles de concentración de iones activos sin perdidas significativas por fluorescencia; y (iii) el tiempo de vida suficientemente largo del nivel emisor de la transición láser asegurando un alto almacenamiento de energía. Estas características son explotadas en este trabajo usando Tm como ion activo para generar emisión láser a 1.94 µm. El máximo local de absorción del agua a esta longitud de onda hace a este laser interesante para aplicaciones medicas y atmosféricas. Cambio de polarización, operación en dos longitudes de onda, laser vibrónico, diseño láser de capa delgada Thin-disk, Q-conmutado pasivo y la interacción láser-tejido del láser de Tm:KLu(WO4)2 a 1.94 µm son demostrados en este trabajo.
Monoclinic potassium lutetium double tungstate KLu(WO4)2 is established as new laser host for Tm, Yb and Ho active ions due to (i) its very high values of absorption and emission cross sections (ii) its relatively large Lu-Lu distances allowing high ion concentration with minimum fluorescence quenching effects and (iii) the long lifetime of the upper laser level ensuring high energy storage. These characteristics are exploited in this work using Tm as active ion to generate laser emission at 1.94 µm. The local maximum of water absorption at this wavelength makes this laser interesting for medical and atmospheric applications. Polarization switching, dual-wavelength operation, vibronic laser, thin-disk laser design, passive Q-switching and the laser-tissue interaction of the 1.94 µm Tm:KLu(WO4)2 laser are demonstrated in this work

Resumen
Du fait de leur compacité, leur robustesse et leur faible coût, les microlasers impulsionnels nanosecondes constituent des sources particulièrement attractives pour de nombreux systèmes de détection et d'analyse, en particulier les cytomètres en flux ou les dispositifs pour la spectroscopie CARS (Coherent Raman Anti Stokes Scattering). Cependant, ces applications nécessitent des performances améliorées en ce qui concerne la gigue temporelle et la cadence de répétition accessible. Dans sa première partie, cette thèse propose des solutions originales pour atteindre les performances requises à partir de microlasers passivement déclenchés, grâce à la mise en oeuvre d'une cavité hybride couplée, pompée par une onde modulée en intensité. Une cadence de répétition supérieure à 30 kHz avec une gigue demeurant inférieure à 200 ns est atteinte. Le potentiel de microlasers à fibres déclenchés par modulation du gain pour monter en cadence est aussi évalué, montrant que des impulsions à faible gigue, à une cadence de plus de 2 MHz peuvent être produites. Enfin, la dernière partie est consacrée à la mise au point et à l'exploitation d'un nouveau système de spectroscopie CARS assisté par une excitation électrique haute tension. Ce dispositif, réalisé à partir d'un microlaser amplifié, permet de s'affranchir du bruit de fond non résonnant des mesures et de réaliser une analyse spectroscopique fine de la réponse de différents milieux d'intérêt sous champ continu ou impulsionnel, pouvant conduire à une nouvelle méthode de microdosimétrie de champ. Diverses applications, dont la granulométrie à l'échelle micro ou nanométrique ou l'identification de marqueurs pour la biologie, sont démontrées
Thanks to their compactness, robustness and low cost, pulsed nanosecond microlasers are particularly attractive sources for different detection and analysis systems, particularly flow cytometers or devices for CARS (Coherent Anti Raman Stokes Scattering) spectroscopy. However, these applications require reduced time jitter and increased repetition rate. The first part of this thesis proposes novel solutions to achieve the required performance from passively Q-switched microlasers, which are based on an hybrid coupled-cavity and intensitymodulated pump wave. A repetition rate greater than 30 kHz with jitter remaining lower than 200 ns is reached. Pulsed fiber microlasers operating by gain switching are also studied, showing that pulses with low timing jitter, at a repetition rate of more than 2 MHz can be obtained. The last part is devoted to the development and the implementation of a new system of CARS spectroscopy assisted by a high-voltage electrical stimulation. This device, based on an amplified microlaser, allows to substract the non-resonant background noise in the measurements. Thus, a fine spectroscopic analysis of the response of different environments of interest in continuous or pulsed field can be achieved. It may lead to a new method for field microdosimetry. Various applications, including granulometry at the micro or nanometric scale and the identification of markers for biology, are shown

Resumen
Les microlasers emettant a 1,55 m sont des lasers solides de faible volume (<1 mm#3) a base de verre : er, yb dont les miroirs de la cavite sont directement deposes sur le milieu a gain. En introduisant un modulateur dans la cavite, il est possible de declencher le laser afin d'obtenir des impulsions de puissance crete elevee donc exploitables pour des applications telles que la telemetrie. L'objet de cette these est d'utiliser un dispositif a semiconducteur comme modulateur. De par leurs proprietes optiques et electriques, les semiconducteurs presentent un fort potentiel pour le declenchement passif et le declenchement actif. Les structures etudiees sont des couches epaisses et des structures a puits quantiques constituees d'in#xga#1##x##yal#yas epitaxiees sur un substrat d'inp. En declenchement passif dans une configuration microlaser, les meilleurs resultats ont ete obtenus avec une couche epaisse de 80 nm d'in#0#,#4#8ga#0#,#5#2as. Les energies et les puissances cretes par impulsion sont respectivement de 2 j et 2w avec un substrat d'inp semi-isolant et, 25 nj et 5w avec un substrat d'inp non dope. Ces differences dans les performances sont dues a des effets non-lineaires associes au substrat d'inp semi-isolant qui elargissent les impulsions. En declenchement actif, les premiers essais en cavite externe ont montre qu'il est possible de moduler l'emission laser en appliquant des creneaux de tension inferieurs a 20v pendant 1 s aux bornes d'une diode p. I. N dont la region intrinseque se compose de 10 puits quantiques d'in#0#,#5#3ga#0#,#4#7as dans des barrieres d'in#0#,#5#2al#0#,#4#8as. Afin d'optimiser l'effet du champ electrique, une structure mesa et une passivation ont ete realisees.

In this paper, we investigate an all-solid-state passive Q-switched Nd:YVO4 laser system. Q-switching operation is very common and important for diode-pumped solid-state lasers. And in recent years, Q-switched lasers have been used in many fields, such as nonlinear optics, range finding, medicine, and micromachining, etc. In this experiment, we use GaAs wafer as an important element for passive Q-switching. The GaAs wafer, which works as an saturable absorber, was used as the Q-switch in the laser system. Moreover, GaAs wafer also acts as an anti-resonant Fabry-Perot resonantor, so we use it as an output coupler. Its reflectance is 73.5%, and its transmittance is 26.5%. We use two gain media with different lengths. One is 6 mm, and the other is 3 mm. The results of this experiment are as follows: The cavity length is adjustable from 8 mm to 17 mm；the shotest pulse width is 7 ns；its photon lifetime is about 0.33 ns；the highest peak power is 314 W；the highest repetition rate is about 1.7 MHz；its pulse energy is up to 2.2 μJ.

Extremely short (1.6 ns) high-peak-power (> 10 kW) pulses of lasers at the eye-safe wavelength region about 1.5 �慆 are obtained by intracavity optical parametric oscillators (OPOs). We demonstrated a compact efficient eye-safe OPO pumped by a diode-pumped passively Q-switched Nd:GdVO4 laser to produce peak powers at 1571 nm higher than 20 kW with pulse widths of 0.7ns . On the other hand, we overcome the instablility in the IOPO by using two-mirror structure .At the same time, we raise the pulse energy to 1.5 times. Due to its stability, we try to apply the two-mirror structure to tune wavelengths by temperature. As a result, we can get the curve slope about 0.4nm/0C. By the way, using Nd:Gd0.7Y0.3VO4 crystals may get 3 times the pulse energy by using Nd:YVO4 crystals and 1.8 times the pulse energy by using Nd:GdVO4 crystals.
