摘要：

The KDP crystal antireflective coatings prepared by spin coating method were discussed. The coating was modified using hexamethyl disilazane (HMDS), and had good moisture-resistant property. Some technique problems such as clamping safety during the spin process were analysed. The coating uniformity, the transmittance, moisture-resistant property and the laser induced damage threshold (LIDT) were measured. The transmittance ununiformity of the coating was about 0.3%, the transmittance at 1053 nm was over 99.8%, the water contact angle was over 152°, and the LIDT was about 10 J/cm2 (355 nm, 3 ns).
