Abstract

Abstract

The thermalelastic model of laser irradiating optical material is established. Analytical method is applied to study the tensile profile induced by laser irradiation in disk sample, and the laser induced damage thresholds are evaluated independently under three mechanical boundaries: free, fixed and arbitrary. The results show that mechanical boundaries have great influence on laser induced damage threshold(LIDT), and optimal boundary under which tensile stress is eliminated is available theoretically when particular arbitrary boundary is applied.
