摘要
文中给出一种简单而灵敏的单光束非线性折射率n2大小测量和符号表示的方法z-scan。样品在聚焦的高斯光束z方向上移动,得到远场小孔处的透过率分散曲线,由这条曲线计算出n2,测得n2=-1.32×10-4esu。
A simple and sensitive method of measuring and signalizing the non-linear refracting power of single Z of focusing Gaus lightbeam and gives rise to the transmissivity curve at the aperture in the distant field.From the curve n2 is obtained; n2-1. 32x10-4 esu.
