New method to measure the surface deformation of optics irradiated by high-power laser and new way to stimulate its influence on beam quality

Abstract

A new method was proposed to measure the surface deformation, where the optics is irradiated by a high power laser when they are measured with ZYGO interferometer. The fiber with output shaper was used to transmit the laser. With this simple and convenient method, measuring k9, fused silica and antireflection coated silica windows, where a power of 200W… (More)
