| 摘 要： | 本文详细地讨论了光学双稳性(OB)的临界现象。理论分析主要以忽略量子涨落的Fokker-Plank方程的静态解为基础。结果发现,OB的临界现象可以纳入Landau二级相变理论的框架,并且有关临界指数之间的关系也服从标度律。关键词：

| Abstract: | Critical phenomena in optical bistability (OB) are studied in some detail. Theoretical an-alyeses, mainly based on the steady solution of the "thermodynamic" Fokker-Plank equation for absorptive OB, show that the critical phenomena in OB also can be brought into the framework of Landau's theory of scond-order phase transitions, and the relations between different kinds of critical index numbers obey the scaling laws. |
