Paper Abstract

Criteria of selecting the slab size in high-power end-pumped Nd:YAG zigzag amplifier were given, the optimized slab thickness is suggested 2~3 mm, with the corresponding slab length less than 15 cm. Power extraction in the slab was calculated by a smart ray tracing technique, the optimized input flux is 3~4 times the saturated flux (Is) with a maximum optical-optical (o-o) efficiency of 44.5% for the single-slab single-pass stage, and 0.1~0.2 Is with a maximum o-o efficiency of 41% for the four-slab angularly double-pass stage.
