摘要
The Cu-doped'KNSBN crystals have been grown.The self-pumped phase conjugate mirrors of Cu-doped KNSBN crystals have been demonstrated.The phase conjugate reflectivity reaches as high as 68% for the crystal with 0.04 wt.%Cu-doped.The phase conjugate reflectivity and its response time were also measured as a function of the argon-ion laser wavelengths.
