As part of this thesis several studies will be presented. The first presentes the problem of preservation of information in a Brillouin amplification process. The second focuses on the achievement of a Brillouin amplifier with a broad bandwidth. The last part concerns the achievement of Brillouin lasers of high coherence. An experimental study of the transition between Brillouin generator and Brillouin amplifier in a state of saturation is performed. It highlights the transfer of energy from the generator to the probe. We have proven that even in a regime of powerful generator, the spectral qualities of the probe are preserved when the resonance is reached. The qualities of the Brillouin amplifier lead us in a second part to try to increase its bandwidth as narrow band gain is a limitation for many applications, especially in the field of telecommunications. We explore the possibility of working with a large-band pump to achieve broad band amplification. We prove a bandwidth above 10 GHz. We demonstrate a monomode laser, with a spectral width below one kHz, stable in frequency and intensity, in which the threshold is reached by commercial DFB laser diodes. The set-up is compact, robust and cost effective. The cavity can also be used separately, ie without pump assigned, to applications of spectral narrowing or filtering. Finally, the application of the device to spectral characterization of coherent lasers is proved and discussed

The laser facilities designed to realize laser inertial confinement thermonuclear fusion experiments use numerous laser beams in order to meet irradiation symmetry constraints and to deposite enough energy in matter. Unfortunately, the crossing of laser beams in plasmas modifies their propagations. When a beam is propagating in plasmas, it can interact with ion acoustic waves and scatter its energy by stimulated Brillouin scattering. Not only the directions but also the levels of these scatterings are modified when beams are crossing one another in plasmas. This manuscript is about the experimental study of two kinds of multiple-beam modification:- the flexibility of the LULI2000 laser facility (Laboratoire d'Utilisation de Lasers Intenses, Palaiseau, France) enabled us to study crossed-beam energy transfer between two and three beams;- the sixty laser beams available on the OMEGA facility (Laboratory for Laser Energetics, Rochester, United-States) enabled us to observe scattering of collective Brillouin instabilities produced in planar geometries and at the entrance hole of cavities of fusion experiments.These two mecanisms can highly modify the initial laser irradiation by transferring up to 30% of the laser energy between beams and by scattering more than 10% of the laser energy in unusual directions
