采用朗之万量子理论讨论双光子双模激光近阈运行的模式耦合.耦合的特性,既可以呈现相互支持和模2被支持模1被抑制的情形,也可以呈现模1被支持模2被抑制和一模被支持另一模既不被支持也不被抑制的情形.耦合的特性不但取决于双模的失谐量,而且取决于三能级的初始布居数.Mode coupling of a two-photon two-mode laser operating near above threshold is discussed with Langevin quantum theory. Characteristics of the coupling shows not only the mutual enhancement of the two modes, as well as the enhancement of mode 2 with suppre
