对多种掺杂浓度、长度的Ｎｄ：ＹＶＯ_４ 晶体进行了吸收性质、激光性质的研究和对比，根据实验结果和测得的上能级寿命计算了不同掺杂浓度Ｎｄ：ＹＶＯ_４ 晶体的有效受激发射截面，对激光二极管端面泵浦Ｎｄ：ＹＶＯ４ 固体激光器的最优化有实际指导意义
The absorption and laser properties of Nd: YVO_4 crystals with various doping concentrations and lengths were studied and compared. Based on the experimental results and the measured upper level lifetimes, the effective doping levels of Nd: YVO_4 crystals with different doping concentrations were calculated Emission cross-section, the laser diode end-pumped Nd: YVO4 solid state laser has practical practical significance of the guide
