Abstract

The damage threshold of an Au-coated flat mirror, one of the reflective optics installed on the FEL-2 beamline of the Dalian Coherent Light Source, China, upon far-UV free-electron laser irradiation is evaluated. The surface of the coating is characterized by profilometer and optical microscope. A theoretical approach of the phenomenon is also presented, by application of conventional single-pulse damage threshold calculations, a one-dimensional thermal diffusion model, as well as finite-element analysis with ANSYS.

摘要

对安装在中国大连相干光源FEL-2光束线上的反射光学元件之一——镀金光镜在远紫外自由电子激光辐照下的损伤阈值进行了评估。通过轮廓仪和光学显微镜对涂层表面进行了表征。还通过应用传统的单脉冲损伤阈值计算、一维热扩散模型以及使用ANSYS进行有限元分析，提出了该现象的理论方法。
