引言研究固体材料的激光损伤时，特别注意损伤阈值时的记录。它的可靠性和精度对分析激光损伤机理有重大意义。使用方法的多样性由研究损伤的不同方面及其相互作用决定。由于光学材料表面和涂层的激光损伤阈值通常低于相应样品的体损阈值，其监察和测量是一个经常需要解决的问 INTRODUCTION Special attention has been paid to the recording of damage thresholds when studying laser damage in solid materials. Its reliability and accuracy of the laser damage analysis of great significance. The diversity of methods used is determined by the different aspects of the study of damage and their interactions. Since the laser damage thresholds on optical material surfaces and coatings are typically below the body damage threshold of the corresponding sample, its monitoring and measurement is often a problem to be solved
