摘　　要：介绍了一套355nm紫外激光损伤阈值自动测量装置。该测量装置由一台Nd:YAG激光器产生紫外355nm激光,经过紫外激光传输系统,紫外激光聚焦形成测试激光。脉冲激光能量由激光能量计监测,Normaski显微镜判断样片的激光损伤。另外,整个测量装置和测量过程由计算机集成控制,具有良好的操作性和运行参数控制能力,可实现1-on-1,n-on-1,s-on-1,R-on-1等多种激光损伤测试。In this paper, the automatic measurement device of 355nm laser damage threshold has been introduced in details. The 355nm ultraviolet radiation produced by Nd:YAG laser device is focused to probe the sample. The pulse energy is monitored by EM500 energy meter and the sample damage is determined by 100X Normaski microscope. In addition, the measurement device and damage measurement process are integrated and controlled by computer software, which has friendly operation and command ability. So the damage measurement device can process the damage threshold measurement such as 1-on-1, n-on-1, s-on-1, and R-on-1, etc.
