一种提高高功率激光系统传输管道内壁抗杂散光损伤阈值的方法
摘要：
本发明公开了一种提高高功率激光系统传输管道内壁抗杂散光损伤阈值的方法，属于激光光学技术领域，其方法是在所述高功率激光系统传输管道内壁设置涂层，所述涂层为抗激光损伤阈值高于金属表面4倍-10倍的透明硅氟橡胶；通过本发明的方法，可以使得入射至金属表面的激光能量密度降低4倍-10倍，从而实现高功率激光系统传输管道内壁抗杂散光损伤阈值的提高。
摘要（英）：

The invention discloses a method for increasing a stray light damage resistance threshold of the inner wall of a high-power laser system transmission pipeline, and belongs to the technical field of laser optics. The method comprises the steps that a coating is arranged at the inner wall of the high-power laser system transmission pipeline, and the coating is transparent silicon-fluorine rubber with the laser damage resistance threshold 4-10 times higher than the surface of metal. According to the method, the energy density of laser emitted into the surface of the metal is lowered by 4-10 times, and therefore the inner wall of the high-power laser system transmission pipeline is increased.
