摘要
针对光折变晶体响应慢的问题,提出了一种预置光栅技术,该预置光栅可由另外的独立预置光源产生 通过对采用预置光栅的光折变晶体自泵浦相位共轭特性及其物理机制进行的实验研究证实,采用预置光栅技术可以大大缩短低重复频率、窄脉冲信号光的光折变自泵浦相位共轭的响应时间,因此对于低重复频率。
A preset grating technique was put forward for slowly response characteristic of photorefractive crystal. This technique can be achieved by preset laser source independent with signal beam. The characteristic and physical mechanism of SPPC based on preset grating were studied experimentally. It indicated that response time of photorefractive SPPC can be deduced greatly and has great practical value for the low repeat, narrow pulse beam.
