在高功率激光器内部激光工作物质和光学元件,窗口镀膜材料的设计中,传能光纤以及制导传感器抗激光致盲材料的设计中,对材料的抗激光性能问题都要有所考虑.大量实验表明,材料表面和界面是较容易损伤的部位.现有的研究大都注重体材料损伤过程的描述上,而对材料界面的激光损伤微观机制的研究甚少.在抗激光材料的设计中,很需要对材料的微观过程有深入的认识.通过对微观过程的分析,引出一些可控制的物理参量,如调制掺杂异质结的调制掺杂浓度.在材料设计中通过调节这些可控制参量,从而使材料能承受某一功率范围的激光辐照.
In the design of laser working substance and optical element, window coating material in high-power laser, design of anti-laser blinding material and transmission fiber, the anti-laser performance of the material should be taken into consideration.A large number of experiments show that , The material surface and the interface are easier to damage.The existing researches mostly focus on the description of the material damage process, but few studies on the micro-mechanism of the laser damage on the material interface.It is necessary to design the anti-laser material Through the analysis of microscopic processes, some controllable physical parameters, such as the modulation doping concentrations of the doped heterojunction, are derived, and by adjusting these controllable parameters in the material design, Enables the material to withstand laser irradiation of a certain power range.
