中文摘要：
报道了连续激光二极管单端抽运Nd：YVO4环形腔结构的单频激光器实验研究。为了减小激光器的热效应,实验中采用了一种新型的抽运结构形式并获得了良好的实验效果。在室温下工作物质采用自然散热,当抽运功率为22.5 W时,获得了9.9 W的1064 nm单频激光输出,对应的光-光转换效率约为44.1%;光束质量为M2x=1.14和M2y=1.12;输出激光1 min内频率漂移约为83.7 MHz;7 h功率不稳定度优于0.5%。
英文摘要：
The experimental results of continuous laser diode pumped Nd：YVO4 ring cavity configuration single frequency laser are reported.To reduce the influence of heat effect in laser,a new pump configuration is designed and better results are achieved.At room temperature,1064 nm single frequency laser with the power up to 9.9 W is obtained from pump power of 22.5 W.Optical-optical conversion efficiency is about 44.1%.Beam quality is M2x=1.14 and M2y=1.12.Frequency excursion is 83.7 MHz in one minute.Instability of output power is less than 0.5% in 7 h.
