摘要

本文综述了俄罗斯联邦核中心实验物理研究所在广泛激光器(气体和固态)SBS反射镜的研究中所取得的结果:新的可能性和新的结果。特别注意了sbs反射镜气体介质的制备和进口问题。我们给出了SBS电池的参数和各种气体混合物在各种压力和密度下的特性,也包括临界点附近的特性和液化气的特性。我们给出了在脉冲长度从2ns到几十微秒的单脉冲或脉冲频率高达数百kHz的重复脉冲辐射下,与SBS竞争的过程的实验结果。实验证明了SBS介质中热变形和伸缩变形自补偿的可能性。在考虑辐射自作用的条件下,我们制定了SBS镜面操作混合物的选择标准。

SBS Mirrors for High Power Lasers
This paper is an overview of results obtained in investigations of SBS-based phase-conjugated devises: new possibilities and results achieved at the Institute of Experimental Physics of the Russian Federal Nuclear Center on development of SBS mirrors for a wide range of lasers (gas and solid-state). Special attention has been paid to questions of preparation and inlet of the SBS-mirror gas media. We give the SBS cell parameters and characteristics of various gas mixtures in a wide range of pressures and densities also including characteristics near the critical point and of liquefied gases as well. We give experimental results from investigations of processes competing with SBS at pulse lengths from 2ns to tens of microseconds when irradiated by single pulse or repetitively pulsed radiation with the pulse rate up to hundreds of kHz. The possibility of self-compensation of thermal and striction distortions in the SBS medium has been demonstrated experimentally. We have formulated criteria for selection of mixtures for SBS mirror operation under various conditions taking into account radiation self-action.
