摘要
采用Ｈａｋｅｎ的全量子理论和双光子激光器定态几率密度方程，考虑了不同的泵浦参量，利用Ｋｒａｍｅｒ近似方法，计算了双光子激光器中光学双稳态的平均开关时间，指出系统中的两个稳态并非同等稳定。事实上，系统可能以亚稳态存在。
Mean switching time of a two-mode laser is calculated in Kramen's methed by properbility density equation of Haken's theory, in which different pump parameters are considered,and it is shownthat the two stationary states of the system are not equally stable. In face. the system can exist in metastable states.
