Research on medium for ultrashort pulse laser by SBS

Picosecond lasers have been widely used in many fields. Compressing nanosecond laser pulses to picosecond-level ultrashort pulses is one of the common methods of obtaining high-energy picosecond pulsed lasers. The pulse compression system based on Brillouin scattering has simple structure,low cost,and is a relatively popular technological method in recent years The key technology of the Brillouin scattering pulse compression scheme lies in the study of the medium. In this paper,by studying the chemical properties,physical properties and compression effects of the three types of media currently applied,the requirements of stimulated brillouin scattering (SBS) on the media and the development direction in the future are analyzed by comparing the research status at home and abroad.
