Beam shaping and compensation for high-gain Nd:glass amplification
TL;DR: In this paper, the beam shaping and compensation for a high Nd:glass amplification system based on the liquid crystal spatial light modulation technique was reported. And the structure of image transfer was confirmed to be capable of maintaining high-quality image transmission in the amplification process.
