The Current Trends in SBS and phase conjugation

Abstract

The current trends in stimulated Brillouin scattering and optical phase conjugation are overviewed. This report is formed by the selected papers presented in the “Fifth International Workshop on stimulated Brillouin scattering and phase conjugation 2010” in Japan. The nonlinear properties of phase conjugation based on stimulated Brillouin scattering and photo-refraction can compensate phase distortions in the high power laser systems, and they will also open up potentially novel laser technologies, e.g., phase stabilization, beam combination, pulse compression, ultrafast pulse shaping, and arbitrary waveform generation.

Research on the compression properties of FC-3283 and FC-770 for generating pulse of hundreds picoseconds

“…Pulse compression by SBS is to use SBS effect leading to a quick energy transfer from pump to the Stokes whose pulse front edge is prior to be amplified. Since it is non-linear exponential growth process, the compressed pulse with high efficiency is very suitable to amplify the Stokes as pulse signal with high energy efficiently (Damzen et al, 1983a;1983b;Hon et al, 1980;Gao et al, 2012;Shin et al, 2010;Omatsu et al, 2012), and the Stokes pulse peak power could increase to dozens of times. We could make use of this process to obtain picoseconds laser pulse with high power.…”

High Compact, High Quality Single Longitudinal Mode Hundred Picoseconds Laser Based on Stimulated Brillouin Scattering Pulse Compression

“…That means that the mode-locked picosecond laser cannot meet the application requirements in those fields. The stimulated Brillouin scattering (SBS) phenomenon was discovered decades ago and has been widely used in phase stabilization, pulse compression, beam combination and ultrafast pulse shaping [13]. Among them, in the field of laser pulse compression, SBS is an effective method to compress a long pulse for its high energy reflectivity and high compression ratio.…”

Effect of amplified spontaneous emission and parasitic oscillations on the performance of cryogenically-cooled slab amplifiers

“…In order to provide highly efficient laser sources, special care has to be taken with the design of the laser system. In order to increase the output energy of a laser and maintain its repetition rate, many different techniques are used including beam combining methods such as stimulated Brillouin scattering phase conjugate mirrors (Kong et al, 2008;Omatsu et al, 2012).…”
