摘　　要：为了研究多模耦合效应,从兰姆半经典自洽场理论出发,采用三阶微扰方法,对Ja=1→Jb=2跃迁的四频环形激光器进行了理论推导,得出了非多普勒极限普遍情形下并含粒子数脉动效应的兰姆系数解析表达式。此结果具有一定的普适性,对定量研究多模耦合精细效应是有帮助的。In order to study the laser multi-modes coupling effects,theoretical deduction of four frequency ring laser at Ja=1→Jb=2 transition was conducted with the third-order perturbation method from the Lamb semi-classical self-consistent theory. The Lamb coefficients in the non-Doppler limit general case including the population pulsation effects were derived. The analysis shows that the conclusion drawn can be generally applied, which is helpful to the quantitative study on the laser multi-modes coupling fine effects.
