摘要
为减少热透镜效应的影响,获得高光束质量的激光,本文利用激光二极管阵列双端直接抽运Nd:YVO4,采用负支共焦折叠混合腔结构,获得最高功率为416 W 1064 nm的激光输出,光—光转换效率为54.3%,斜效率为61.6%.在输出功率为370 W时,光束质量因子M2在非稳腔和稳腔方向上分别为3.9和4.7.
To reduce the influence of thermal lensing and attain the high power laser with high beam quality, a laser diode stack dual-end-direct-pumped Nd：YVO4 slab laser with negative branch confocal folded hybrid cavity has been developed. Its maximum output power is 416 W, optical conversion efficiency is 54.3%, and slope efficiency is 61.6%. When the output laser power is 370 W, M2 values in the unstable resonator direction and stable resonator direction are 3.9 and 4.7, respectively.
