| 摘 要： | 针对光折变效应响应慢的问题，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互泵浦相位共轭特性及其物理机制进行的实验研究证实，采用这种预置光栅技术可大大缩短低重复率、窄脉冲信号光的光折变互泵浦相位共轭响应工作时间．

| Abstract: | a preset grating technique is put forward for slow response characteristics of the photorefractive crystal. This technique can be achieved by the preset laser independent of the signal beam. The characteristics of MPPC based on preset grating and its physical mechanism are studied experimentally. It is indicated that the response time of photorefractive MPPC based on preset grating can be reduced greatly, and hence this technique is of great practical value for the application of MPPC with a lowly repeated narrow pulse beam. |
