可调谐中红外OPO激光器研究

摘要

研究了一种中红外可调谐OPO激光器,泵浦源为输出能量200 mJ能量的1.06 μmNd:YAG激光器,OPO采用XZ平面内二类匹配的KTP-OPO,实现了信频光1.5～2.0 μm、闲频光2.3～3.6 μm的波长调谐,光光转换效率10％以上.%Presented in this paper is the study of a mid-infrared tunable OPO laser with a pump source of 200 mJ, 1. 064μm Nd:YAG laser. The OPO uses type two matching KP-OPO in XZ plane. Signal-frequency of 1. 5～2. 0μm and idler frequency of 2. 3 ～3. 6 μm are obtained. The wavelength is continuously tunable. The light to light conversion efficiency is better than 10% .
