摘要
文中基于Nd∶GdVO4晶体的能级结构和速率方程理论,对激光二极管端面抽运Nd∶Gd-VO4固体激光器的输入输出特性参数进行了理论研究。通过数值计算得到了其振荡光的光斑与抽运光斑的匹配程度、增益介质的长度、腔内固有损耗和输出镜透过率的最佳值,并通过与激光二极管抽运Nd∶YAG固体激光器的输出特性进行比较,获得了在相同条件下Nd∶GdVO4晶体的输出特性优于Nd∶YAG晶体的高功率端面抽运的全固态激光器,其理论值与实验结果一致。
The thoroughgoing theoretical analysis of the characteristic parameter of input and output of laser-diodepumped Nd：GdVO4 solid-state laser has been carried out on the basis of Nd：GdVO4 crystal level structure and the rate equation theory. The optimum values of the degree of mode matching of resonant light spot and pump light spot, the length of gain medium,the intracavity intrinsic loss,and the output mirror transmission have been obtained by numerical simulation. Furthermore,compared with the output characteristic of Nd：YAG solid-state laser pumped by LD, the output property of Nd：GdVO4 solid-state laser which is much better than that of Nd：YAG has been obtained in the same conditions.
