| 摘 要： | 采用离子辅助沉积技术在LiB3O5晶体上制备了946nm,473nm倍频增透膜,并测量了薄膜的性质.测试结果表明, 该增透膜具有较低的剩余反射、高的环境稳定性和良好的附着力.进一步测量了薄膜在波长1064nm多脉冲辐照下的激光损伤阈值,获得了两种不同的损伤形貌,并对损伤原因作了初步的探讨.此工艺下镀制的LiB3O5晶体用于瓦级全固态蓝光激光器,获得了3.8W波长为473nm的连续蓝光输出.

| Abstract: | Frequency doubling antireflection coatings at 946nm and 473nm were deposited for LiB_3O_5 crystal with ion assisted deposition.The measurement indicates the coatings have low residual reflection,good adhesion and high environmental stability.Laser induce damage threshold by multiple-shot irradiation at 1064nm was studied and two typical damage morphologies were obtained.LBO devices coated on both facets with ion assisted deposition are satisfied with the use for CW Watt-level All-solid-state 473nm blue laser.The maximum laser output power of 3.8W has been achieved at 39W of pump power. |
