| 摘 要： | 在KNSBN：Ce晶体中，利用二波耦合作用，在单一光束无法获得相位共轭光的条件下，实现了“猫”式互抽运相位共轭光输出，获得较高的共轭光发射率，实验结果表明，晶体的二波耦合作用可以使晶体的自抽运相位共轭光的阈值光强降低。入射光的入射角范围增大，响应时间缩短。

| Abstract: | Cat mutually pumped phase conjugation configuration are discovered and investigated by using two wave mixing in KNSBN crystal. When only one signal or pumped beam does not give birth to phase conjugation, the maximum reflectivities of the signal and pumped beam are attained to be 140% and 30% due to two wave mixing, respectively. The results of experiment show that the two wave mixing effect can reduce the threshold of incident beam power, extend the incident angle range and shorten the response rate in the process of self pumped phase conjugator in the KNSBN crystal. |
