摘要: 报道了一种基于914 nm共振泵浦技术的高效主动调Q Nd：YVO4自拉曼激光器。将处于基态低斯塔克能级粒子直接泵浦到激光上能级，可以减小斯托克斯因子损耗、降低量子亏损，从而实现了高效的1 176 nm拉曼光输出。在共振泵浦条件下，对泵浦吸收对转换效率的影响进行了详细的实验研究。使用两块掺杂浓度不同的Nd：YVO4晶体，分别获得了1.51 W （1.0-at.%，20℃）和2.11 W （2.0-at.%，20℃）的平均输出功率，对应的光光转换效率分别为28.5%（1.0-at.%）和35.2%（2.0-at.%），相对于吸收泵浦光的转换效率分别为42.7%（1.0-at.%）和39.0%（2.0-at.%）。

Abstract: An high efficient actively Q-switched Nd:YVO4 self-Raman laser based on in-band pumped at 914 nm was reported. Particles from thermally excited Stark leveled in the ground-state were pumped to the upper lasing level directly, the Stokes factor loss was reduced to a minimum and the quantum efficiency loss was eliminated. This alleviated the thermal effect of the laser and consequently realized better performance. The effect of pump absorption on conversion efficiency was investigated experimentally in detail with the in-band pumping. Using two Nd:YVO4 crystals with different doping concentration, 1.51 W(1.0-at.%, 20℃) and 2.11 W(2.0-at.%, 20℃) output power were obtained respectively, corresponding to the conversion efficiency of 42.7%(1.0-at.%) and 39.0%(2.0-at.%) and the optical efficiency of 28.5%(1.0-at.%) and 35.2%(2.0-at.%).
