分析了Nd∶SVAP晶体在X(a)-轴和Y-轴不同切割情况下的偏振吸收和荧光谱,并对沿不同方向切割样品的激光特性进行了研究。发现沿X轴方向切割样品的荧光谱的偏振度为4.41,而沿Y轴方向切割样品的偏振度为2.18。并且,沿X轴方向切割样品的π偏振荧光谱的强度是沿Y轴切割样品的1.7倍。还报道了对激光器输出中心波长与泵浦功率大小的关系以及输出功率的大小与激光晶体温度关系的研究结果
The polarization absorption and fluorescence spectra of Nd:SVAP crystal under different cutting conditions of X (a) -axis and Y-axis were analyzed. The laser characteristics of samples cut along different directions were also studied. The fluorescence spectrum of the sample cut along the X-axis was found to have a degree of polarization of 4.41 and that of the sample cut along the Y-axis was 2.18. Also, the intensity of the pi-polarization fluorescence spectrum of a sample cut in the X-axis direction was 1.7 times that of the sample cut along the Y-axis. Also reported on the laser output center wavelength and pump power and the relationship between the size of the output power and laser crystal temperature relationship between the results of the study
