| 摘 要： | 以单晶硅作非线性介质,用调Q脉冲Nd:YAG激光作四渡混频,获得了相位共轭反射光波.从光激发电子-空穴对浓度及其所产生的相位光栅出发,理论计算了相位共轭镜的反射率.实验获得的共轭镜反射率为125%,并与实验中显示了其对相位干扰的补偿特性.

| Abstract: | The phase conjugate wave has been obtained by degenerated four-wave mixing (DFWM) with silicon single crystal as the nonlinear medium using Q-switched Nd:YAG lasers. The reflectivity of the phase conjugate mirror (PCM) has been calculated from the theory of the light induced electron-hole-pair density, which produced a phase grating. Experimentally, a reflectivity of 125% of the PCM was obtained and the property of the compensation of the phase aberrations was demonstrated. |
