摘　　要：报道了利用光纤耦合大功率半导体激光器 (LD)抽运Nd∶GdVO4晶体 ,采用平凹谐振腔 ,输出 1 34μm波长的高功率连续波固体激光器。在抽运功率为 1 4 75W时 ,获得最大输出功率为 4 6 2W ,光 光转换效率为 31 3% ,斜率效率达 32 9%。利用实验测得的阈值抽运功率和斜率效率 ,计算了Nd∶GdVO4晶体在 1A high power continuous wave 1.34 μm Nd∶GdVO 4 laser end pumped by laser diode array with plano concave resonator was reported. At the incident pump power of 14.75 W, the maximum output power of 4.62 W was obtained with the corresponding optical conversion efficiency of 31.3% and the average slope efficiency of 32.9%. By using the experimentally measured threshold data and slope efficiency, the stimulated emission cross section of Nd∶GdVO 4 crystal was determined to be 1.95×10 -19 cm 2.
