| 摘 要： | 本文首次报道了氩离子激光在溶胶CdS半导体毫微晶中产生的自聚焦、热自散焦及自位相调制,实验测得此种材料具有很大的克尔(Kerr)非线性系数n_2,比CS_2大10~5倍。并且,文中还分析了这种具有弱吸收的半导体溶胶毫微晶的非线性自位相调制机理及其与热自位相调制的差别。 |

| Abstract: | The self-focusing, thermal self-defocusing and self-phase modulation of argon ion laser in colloidal CdS semiconductor microcrystallites are first reported in this paper. The large nonlinear optical Kerr coefficient, n2, is measured, and is found to be ～105 times the value for CS2. The differences between nonlinear self-phase modulation and thermal self-phase modulation in the colloidal semiconductor miorocrystallites, which are of weak absorption, are analysed. |
| Keywords: | colloidal CdS miorocryatallitea self-focusing thermal self-defocusing self-phase modulation. |
