Laser-induced bulk impurity damage has always been a difficult issue in optical systems, affecting the signal-to-noise ratio, beam quality, and other vital laser parameters. In this study, the generation mechanism of bulk damage morphology is demonstrated through a combination of experiment and theory. The growth mechanism is then represented through parameter control. Finally, a general conclusion of bulk damage generation is obtained alongside a reasonable control range of dangerous parameters. The damage area is described comprehensively, and the guiding conclusions of dangerous parameters are given, providing theoretical support for precision optics processing, high-power laser design and other projects.

激光引起的体杂质损伤一直是光学系统中的一个难题，影响信噪比、光束质量和其他重要的激光参数。本研究通过实验与理论相结合，论证了体损伤形态的产生机制。然后通过参数控制来表示增长机制。最后，除了危险参数的合理控制范围外，还获得了批量损坏生成的一般结论。全面描述损伤区域，给出危险参数的指导性结论，为精密光学加工、大功率激光器设计等项目提供理论支持。
