【Abstract】 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.更多还原
