Paper Abstract

Bulk laser induced damage in KDP crystal was measured using a single-shot 1-ns pulse Nd:YAG laser in a transverse and longitudinal single mode. It is found that the damage threshold of KDP single crystal depends on the laser irradiation direction, polarization direction and laser wavelength. The damage threshold in the direction of c-axis is about two times higher than that in the a(b)-axis at 0.532 and 1.064-micrometers wavelength. This result consistent with the experimental results that (001) direction is mechanically weaker than (100) direction with the result of mechanical strength tests.
