在289~435 K温度范围内，采用最小偏差法测量了掺有1wt.%钕的铝酸钇晶体(Nd:YAP)的主折射率，在0.5398、0.6328和1.0795μm波长范围内，得到了热折射率系数，热折射率系数均为正值，并随波长的增加略有减小。还给出了 273-420 K 温度范围内单项 Sellmeier 方程的常数。这些常数与温度呈线性关系，误差范围为 4 x 10(-3)。
The principal refractive indices of yttrium aluminate crystal doping with 1-wt.% neodymium (Nd:YAP) have been measured by a minimum deviation method for the wavelengths 0.5398, 0.6328, and 1.0795 microm in the temperature range of 289-435 K. The thermal refractive index coefficients have been obtained at these wavelengths, and they are all positive and slightly decrease with increased wavelength. The constants of the single term Sellmeier equation are also given for the 273-420 K temperature range. These constants are in linear relationship with temperature in the 4 x 10(-3) error range.
