Growth and High Reflectivity Self-Pumped Phase Conjugate of Cu-Doped KNSBN Crystal

Abstract

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.
