Abstract

The laser-induced damage threshold (LIDT) of KDP crystal affect directly the increase of laser power. In order to research the influence of metal impurities in the subsurface of KDP crystal on LIDT, analyzed the impurities composition and relative content of two kinds of KDP crystal samples by fluorescence imaging method. Based on the theory of the thermal conduction equations and the thermal-elastic equations, the LIDT of KDP crystal on finite element method was analyzed. The results indicate that impurities may affect the distribution of temperature field and thermal stress field of the KDP crystal, resulting in a decline in the LIDT of the material, at the same time, different kinds of impurity and the impurity content will also impact on LIDT.
