摘要
报道了一种半导体激光列阵侧面泵浦Nd:YAG四倍频266nm全固态紫外激光器,采用Z型腔结构,Ⅰ类临界相位匹配LBO和BBO晶体分别作为二倍频晶体和四倍频晶体。在调制频率为5kHz时,最终获得了2.1W的266nm紫外激光输出,单脉冲能量420μJ,绿光到紫外激光的转换率为13.13%,在相同的泵浦功率下利用V型腔结构仅获得305mW的266nm紫外激光输出。
An all-solid-state laser diode（LD）-side pumped Nd：YAG ultraviolet（UV） laser at 266 nm is rcporlcd, whicl~ is based on fourth harmonic generation and adopts zigzag cavity structure. The type-Ⅰ critical phase matched LBO and BBO crystals are used as the second harmonic and fourth harmonic generation crystals, respectively, and 2.1 W UV laser of 266 nm with single pulse energy of 420 μJ is obtained at the pulse repetition rate of 5 kHz with the conversion efficiency of 13. 13% from green to ertraviolet light. With V shaped cavity configuration, only 305 mW 266 nm UV laser is obtained under the same condition.
