摘要
本文中我们唯象地提出了一个光学非线性系统的动力学模型,阐明了光学三稳系统的临界现象同样可以纳入朗道相变理论的模式。将相变的朗道理论由原来的双稳系统推广到三稳系统,揭示了不同光学非线性系统在临界点附近的共性。
In this paper a dynamical equation of optical nonlinear systems is put forwardin a phenomenological way.The critical phenomena of optical tritability,like the opticalbistability,are examined by Landau's theory of mean field of phase transition in equilibriumthermodynamics. And the generality in the neighbourhood of this critical point of thedifferent optical nonlinear systems is also illustrated.
