Influence of laser beam size and wavelength in the determination of LIDT

The laser-induced damage resistance of large optical components remains an important limitation for the maintenance costs, reliability, and further development of high-energy laser systems. Traditionally, the laser-induced damage thresholds (LIDT) are performed on small samples and using small laser beam sizes (usually limited by the laser output), but these test results tend to be quite…
