摘　　要：利用自准直法，在303～443K温度范围内，用0．473、0．633、1．064、1．319和1．338μm等波长测量了Nd^3＋：Gd3Ga5O12（Nd：GGG）晶体的折射率，得到了上述波长的折射率温度系数和测量温度范围内修正的Sellmeier方程的常数。用色散方程和折射率温度系数表达式，计算了相应温度下在0．473～1．338μm波段内任意波长的折射率及折射率温度系数。The refractive indices of Nd^3＋：Gd3Ga5O12（Nd：GGG） crystal had been measured by the auto-collimation method at wavelengths of 0.473 ban,0. 6328μm,1. 064 ban,1.319 ban,and 1. 338 ban at the temperature range from 303 K to 443 K respectively. The thermal refractive index coefficients were obtained at these wavelengths and the constants of modified Sellmeier＇ s equation were also obtained at the temperature range The refractive index thermal refractive index coefficient of Nd：GGG crystal can be calculated with the Sellmeier＇s scattering equation and the thermal refractive index coefficient expression at any wavelength within the waveband of 0. 473 tan to 1.338 tan,respectively.
