摘要

本研究评估了中国大连相干光源 FEL-2 光束线的反射镜之一--金涂层平面镜在远紫外自由电子激光照射下的损伤阈值。通过轮廓仪和光学显微镜对涂层表面进行了表征。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 ANSYS 有限元分析，还介绍了该现象的理论方法。

Study on the UV FEL single-shot damage threshold of an Au thin film.

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.
