Abstract

This article introduces the study of peripheral clamping for large-aperture laser mirrors in high power laser facilities. Some multi-point clamping schemes were experimentally tested, the results of the experiments show that these schemes cannot meet the technical requirements, and in the simulation analysis, we explain the reason for this phenomenon. It is concluded that the additional bending moment caused by the non-ideal process factors in the multi-point clamping is the main cause for the surface distortion. Based on the above conclusions, we carried out research on minor-point clamping. Experimental verification of the minor-point clamping were done, the results show that the minor-point clamping can meet the requirements of technical indicators in whole process. This work can provide a reference for the design of the large-aperture transport mirror clamping structure, which may be used in huge laser devices and telescopes.
大口径激光传输镜周边夹持的研究
介绍了大功率激光设备中大口径激光反射镜的周边夹紧技术。对几种多点夹紧方案进行了实验测试,实验结果表明这些方案不能满足技术要求,并在仿真分析中解释了产生这种现象的原因。结果表明,多点夹紧过程中非理想工艺因素引起的附加弯矩是造成表面变形的主要原因。基于以上结论,我们进行了小点夹紧的研究。对小点装夹进行了实验验证,结果表明,小点装夹在整个工艺过程中都能满足技术指标的要求。该工作可为大口径输运镜夹紧结构的设计提供参考,该结构可用于大型激光设备和望远镜。
