Automatic test system for multiwavelength laser-induced damage threshold measurements

Laser-induced damage threshold is an important parameter to evaluate the performance of the optical components in high power laser systems. An automated test system is presented to measure multiwavelength laser-induced damage threshold. The presented system can be able to operate the 1-on-1 and R-on-1 methodologies at 1064nm, 532nm, and 355nm. Some solutions are presented to improve the measurement efficiency and the reliability. Experimental results are also provided to confirm the capabilities of the proposed test system.
