摘要

摘要在测量光辐射吸收系数的基础上，提出了确定非线性光学晶体中激光击穿的标准。演示了使用皮尔斯振荡器实时测定光吸收系数的可能性。考虑到自聚焦效应，所提出的标准被用于确定铌酸锂晶体的光损伤阈值（500 mJ/cm2）。

A New Criterion for Determining Optical Damage of Nonlinear Optical Crystals, Based on the Use of an RF Oscillator Circuit

A criterion is proposed for determining laser breakdown in nonlinear optical crystals, based on measuring the absorption coefficient of optical radiation. A possibility of using a Pierce oscillator is demonstrated to determine the optical absorption coefficient in real time. The proposed criterion is applied to find the optical damage threshold of a lithium niobate crystal, which is 500 mJ/cm², taking into account the self-focusing effect.
