摘要
本文对闪光灯泵浦的饱和增益介质Nd∶YAG中采用偏振正交泵浦光的1.064μm的相位共轭特性进行了实验研究.实验主要分析了相位共轭反射率和相位共轭光能量与小信号增益长度积、泵浦光的能量比以及各光束的光通量密度等参量的关系.实验结果与理论计算吻合较好.而且实验中观测到在弱探测光的情况下超过100%的共轭反射率.最高的相位共轭光能量是0.7 mJ.
In this paper,phase conjugation with orthogonally polarized pump beams at 1.064 μm in the saturable gain of flash-lamp-pumped Nd∶YAG amplifier is investigated experimentally.In our experiment,the dependence of the efficiency of the process on the small-signal-gain length product,beam ratios,and influences is analyzed for transmission grating cases.The experimental results show well agreement with the theoretical predictions.A phase conjugate reflectivity of a weak probe beam higher than 100% and a conjugation beam energy of great that 0.7 mJ are demonstrated.Good agreement in magnitude of the experimental reflectivity to the theoretical predictions is seen.
