摘　　要：用光纤耦合的半导体激光器(LD)泵浦Nd3+:NaY(WO4)2(Nd:NYW)晶体,采用非稳腔法测量了晶体在泵浦功率3.5～6.5W范围内的热焦距,并与理论计算结果进行了比较;同时,测量了不同泵浦功率下的最佳泵浦位置,理论分析计算与实验结果相符合,并对实验现象作出了合理的解释。Thermal focal length of fiber-coupling LD end-pumped Nd: NYW laser were measured within the range of pump power from 3. 5 to 6. 5 W with a method of nonstable cavity, and the results were compared with the theoretical results. Meanwhile, the optimal pump position was investigated under different pump powers. The experimental results are consistent with theoretical prediction and the phenomena are interpreted reasonably.
