Abstract

“Shen-Guang II” (SG-II) and “Shen-Guang III” (SG-III) project have been established to promote ICF research in China. For SG-II laser driver we designed a co-axis double pass disk amplifier and built its prototype. The testing results showed that this scheme was available and had something to recommend it in cost and reliability. On the base, we further suggest a new co-axis four-pass amplifier scheme with SBS phase conjugation mirror and harmonic switch for SG-III. In this paper we will describe its conceptional design.
