用CH_4气体SBBS作为相位共轭镜的（Nd，Ce）∶YAG激光谐振腔特性的研究

Characteristic investigation of (Nd,Ce):YAG Laser Resonator with a Phase Conjugating Mirror Based on SBBS in CH_4 Gas

利用高压ＣＨ４气体中的受激布里渊散射作相位共轭反射镜，组成（Ｎｄ，Ｃｅ）：ＹＡＧ激光腔，获得了６２．７ｍＪ近ＴＥＭ００模的激光脉冲，提出了ＳＢＳ相位共轭谐振腔是由不同腔长的谐振腔叠加的新概念。

Using the Stimulated Brillouin Back Scattering (SBBS) in high pressure CH4 gas as a phase conjugating mirror in a (Nd,Ce): YAG laser resonator, we have got 62.7 mJnear TEMoo mode laser pulses. Also, we have proposed a concept that SBS phase conjugatinglaser resonator is the result of many overlaped resonators of different lengths.
