薄膜 镁掺杂铌酸锂 多波段减反膜 激光损伤阈值 thin film MgO doped LiNbO3 crystal multi-spectral antireflective coating laser induced damage threshold
摘要
采用电子束沉积法在镁掺杂铌酸锂基底上镀制了多波段增透膜, 透射波段分别为1.064 μm, 1.4～1.6 μm和3.5～4.3 μm, 测量了薄膜在1064 nm多脉冲辐照下的损伤阈值, 以及无薄膜铌酸锂晶体本身的损伤阈值。结果表明, 镀膜之后, 晶体的损伤阈值较未镀膜样品明显提高。
Abstract
Multi-spectral antireflective coating (AR) was deposited by electron beam evaporation on MgO doped LiNbO3 crystal, and the transmission band of the coating is 1.064 μm, 1.4～1.6 μm and 3.5～4.3 μm. The laser induced damage threshold (LIDT) of un-coated and AR-coated samples were measured. The AR-coated samples have a better LIDT than un-coated crystal.
