The result showed that EDTA with high concentration has evident effect on light scatter of KDP crystal but not laser damage threshold and homogeneity.
结果表明，高浓度EDTA对KDP晶体光散射有明显的影响，但对光学均匀性和光损伤阈值无明显影响。
Subsurface damage has been the main cause to lower the laser-induced damage threshold of optics components in high power solid laser system, and one important kind of these is scratch.
亚表面缺陷是造成固体激光器光学器件损伤阈值过低的重要原因，而表面划痕是缺陷中重要的一种。
