摘要
利用掺ＣＵ的ＫＮＳＢＮ晶体做成的自泵浦相位共轭镜可以补偿由于热自聚焦效应引起的随时间慢变的空间自调相。即由非线性介质引起的时间慢变的波前畸变可以利用相位共轭技术进行补偿。实验发现、尽管相位共轭反射率在时间上有较大幅度的不规则起伏．但相位共轭镜对波前畸变的补偿仍相当理想。
It is found that the slow change with time of spatial self-phase modulation due tothermal self- focusing effect can be compensated with a self-pumped phase-conjugate mirrormade of Cu .doped KNSBN crystal. The experimental results show that phase-conjugationfluctuates irregularly, but the wave-front distortion can be well corrected with the phaseconjugate mirror.
