TL;DR: In this paper, a new concept of high peak power solid state laser system on the basis of successive amplification of a relatively long pulse (5O-l5Ons) and its effective compression by stimulated Brillouin scattering (SBS) is discussed.
Abstract: A new concept of high peak power solid state laser system on the basis of successive amplification of a relatively long pulse (5O-l5Ons) and its effective compression by stimulated Brillouin scattering (SBS) is discussed. Analyses and experiments indicate that the energy fluence for long pulses can be significantly increased. Such laser system can be more effective more simple and less expensive than traditional master oscillator-power amplifier (MOPA) geometry.

TL;DR: In this article, a new version of a pulse compression scheme based on stimulated Brillouin scattering is proposed, which can work in a wide energy range from 100 mJ to several Joules, with a compressed pulse as short as 150-300 ps.
Abstract: A repetitively pulsed solid-state laser system with a new version of a pulse compression scheme based on stimulated Brillouin scattering is proposed. The scheme allows us to work in a wide energy range from 100 mJ to several Joules, with a compressed pulse as short as 150–300 ps.

TL;DR: In this article, the main optical problems of creating lasers with supershort pulse widths and high peak radiation power are considered, and the role of S. I. Vavilov State Optical Institute in research and development in powerful laser systems is considered.
Abstract: The goal of this article is to consider the main optical problems of creating lasers with supershort pulse widths and high peak radiation power and to give a review of research on this specialization at the State Optical Institute. Fundamental effects that limit the peak power are of the greatest interest, and methods of suppressing them are considered. One such method is to convert to a laser architecture with pulse compression, which makes it possible to sharply improve the characteristics of the radiation by comparison with lasers that use direct amplification of short pulses. This is achieved by suppressing nonlinear effects while amplifying longer laser pulses. The main nonlinear effects that limit the radiation brightness in solid-state lasers and pulse-compression methods for creating a new class of lasers are considered. The role of S. I. Vavilov State Optical Institute in research and development in powerful laser systems is considered in detail.
