【摘要】 采用提拉法生长了高光学质量的 Gd Ca4 O(BO3) 3(Gd COB)晶体 ;测量了 Gd COB晶体不同相位匹配方向上的腔内及腔外二倍频转换效率。在 Gd COB晶体的腔内倍频实验中 ,当输入功率为 10 W时 ,空间方向为 (113.2°,4 7.4°)的样品可产生 1.2 2 W波长为 5 32 nm的绿光输出更多还原

【Abstract】 High quality GdCa 4O(BO 3) 3 (GdCOB) crystal is grown by Czochralski method.Samples are cut in and out of principal planes for type Ⅰ phase matching.Their second harmonic generation (SHG) conversion efficiency is measured by a mode locked Nd:YAG laser and the intracavity doubling frequency of GdCOB crystal is reported.At the incident pump power of 10 W,the 532 nm output reaches 1.22 W with the (113.2°,47.4°) cut sample.更多还原
