Abstract

This article describes the front-end system for the SG-II high power laser facility. The front-end of SG-II is based on amplitude waveguide modulator pulse shaping technology and short pulse laser trigger synchronization technology. A phase modulator is used to broaden the frequency spectrum to suppress SBS effect. And a wide spectrum Nd:glass regenerative amplifier pumped by LD is developed. In order to improve the fill factor of the output laser beam to acquire maximum energy of SG-II, the spatial shaping system is developed to control the intensity distribution.
