| 摘 要： | 具体给出了含可饱和吸收体的单模驻波激光系统的哈密顿(Hamiltonian)量和序参量运动方程,并对序参量的定态解做了线性稳定性分析。结果表明,驻波系统在阈值附近的定态行为(非平衡相变行为、双稳行为、临界点附近的指数行为等)与行波系统定性类似,但具体细节有异。特别不同于行波的是,驻波情形下三个定态解中的I_分支有可能实现。

| Abstract: | The Hamiltonian and equation of motion for the order parameter of a single-mode standing-wave laser system with saturable absorber are given in detail. Three stationary solutions of the equation are obtained near the threshold; their stability is analysed. The results show that the stationary behavior (nonequilibrium phase transition, bistability, critical exponents) of standing wave system near the threshold is similar to the of a traveling wave system qualitatively, but they differ quantitatively. Among she differences, it is worth to emphasize that it is possible to realize I_ (one of the three ttationary solutions) branch experimentally, what is not possible in the traveling-wave case. |
