Paper Abstract

Laser induced materials modifications in the bulk and on the surface of KDP and DKDP are studied using fluorescence image and spectroscopy. Photoluminescence is observed at damaged regions following above threshold exposure with an emission peak centered at 550-nm. In addition, surfaces exposed to > 100 high power, 355-nm laser pulse reveal a reduced surface finishing quality as evidenced by an associated emission under UV photoexcitation. The emission spectra from the laser-induced damage sites and the laser degraded surfaces are similar suggesting the generation of similar defect species.
