| Abstract: | A new method based “Split-combined” principle is proposed to improve the load capacity of stimulated Brillouin scattering
(SBS) phase-conjugating mirror (PCM). The incident light is split into two beams by polarizer, which will respectively produce
SBS in the same experimental conditions, and then the generated two beams of Stokes light are combined together so as to improve
the system’s load capacity. The method is verified in Continuum Nd: YAG seed-injected laser system and use FC-72 as the SBS
medium. The results show that this method not only has a simple structure and high efficiency characteristics, but also improves
the system’s power-load capacity and acquires a better quality linearly-polarized beam, which is expected to provide a new
program for the application of SBS phase-conjugating mirror in a high-power system. |
