Development progress for amplifier of SGIII laser facility

Development plan and some progress have been made for amplifier of SGIII laser facility. According to this plan, a single-segment amplifier has been designed and experimented to test key units and correct simulating codein National Laboratory of Laser Fusion of China. The preliminary design for 4X2X3 amplifier prototypes, including amplifier modules, pulsed power, assembly equipment, and optics for SGIII will be finished.
