利用全固态Nd:YVO4激光器的914nm输出作为抽运源,对Nd:YVO4晶体进行基态高斯塔克能级共振抽运,获得了高效率的1064nm激光输出。为解决基态高斯塔克能级共振抽运吸收差、光-光转换效率低的问题,详细分析了掺杂浓度、温度以及长度等晶体参数对抽运光吸收和激光转换效率的影响。在此基础上,使用长度为20mm的Nd:YVO4晶体获得了相对入射抽运光56.9%的高光-光转换效率。914nm基态高斯塔克能级共振抽运Nd:YVO4激光器的光-光转换效率达到了可与传统抽运相比拟的实用化水平。 Using the 914nm output of an all-solid-state Nd: YVO4 laser as a pump source, the ground-state high-Stokes energy level resonant pumping of Nd: YVO4 crystal was achieved, and a high efficiency 1064nm laser output was obtained. In order to solve the problem of poor absorption and low light-to-light conversion efficiency of ground-state Gaussian energy level resonant pumping, the influence of crystal parameters such as doping concentration, temperature and length on pumping light absorption and laser conversion efficiency were analyzed in detail. On this basis, a high light-to-light conversion efficiency of 56.9% with respect to incident pumping light was obtained using a Nd: YVO4 crystal of 20 mm in length. The light-to-light conversion efficiency of the 914 nm ground-state Gaostak-level resonant pumped Nd: YVO4 laser achieves practical levels comparable to conventional pumping.
