InS_b半导体光学非线性的研究

On the Optical Non-linearity of the Semi-conductor InSb

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.
