The nonlinear refractive index, n2, of sapphire was experimentally measured in the 550-1550-nm wavelength range by use of a picosecond Z-scan technique. It was found that in this spectral region the value of n2 decreases monotonically from approximately 3.3 x 10(-16) to approximately 2.8 x 10(-16) cm2/W. An empirical expression for the wavelength dependence of the nonlinear refractive index in the 270-1550-nm range was obtained.
利用皮秒Z扫描技术在550 - 1550纳米波长范围内对蓝宝石的非线性折射率n2进行了实验测量。发现在该光谱区域，n2的值从约3.3×10^(-16)单调下降至约2.8×10^(-16)平方厘米/瓦。得到了270 - 1550纳米范围内非线性折射率随波长变化的经验表达式。
