报道了一种由波长锁定878.6 nm半导体激光器共振抽运两块不同掺杂浓度Nd:YVO4晶体串接的1064 nm激光器,并与使用单块的低掺杂浓度晶体和高掺杂浓度晶体情况进行比较,实验表明利用波长锁定878.6 nm半导体激光器共振抽运双晶体串接的方式,有利于降低晶体的热效应,提高光光转换效率. 当抽运功率为40 W 时,获得了28.2 W 的1064 nm激光输出,光光转换率为70.5%,斜率效率为70.6%,相对吸收光的光光转换率76%,斜率效率为76.4%,同时该激光器在10 ℃40 ℃的温度变化范围内具有极好的温度稳定性.

We report a wave-locked 878.6 nm diode-laser-pumped multi-segmented Nd:YVO4 laser operating at 1064 nm, which is compared with the high doping concentration and the low doping concentration monolithic Nd:YVO4 lasers. Experimental results show that the configuration of the wave-locked 878.6 nm diode-laser-pumped multi-segmented crystals not only can reduce thermal effects of the laser but also can improve the optical-to-optical conversion efficiency. We have achieved an output power of 28.2 W at 1064 nm with an incidence pump power of 40 W, corresponding to the optical-to-optical efficiency of 70.5%, slope efficiency of 70.6%. For absorbed pump power, the optical-to-optical efficiency is 76% and the slope efficiency is 76.4%. The laser also has an excellent output stability while the temperature is varied from 10 ℃ to 40 ℃.-
