Two different kinds of second harmonic antireflection(AR) coatings, with and without SiO2 barrier layer were prepared with ion assisted deposition on LiB3O5 crystal. Laser induced damage threshold(LIDT) by multiple-shot irradiation at 1 064 nm was studied and two typical damage morphologies were observed by SEM. The AR coatings with SiO2 barrier layer have an excellent LIDT, which is about 40% higher than that of coatings without barrier layer. The mechanism of LIDT enhancement by adding SiO2 barrier layer is also discussed.
