本文假设注入环形腔激光器的信号的横向场分布为TEM_(10)模.利用平均场近似方法得到了单横模共振时的定态方程,并进行了线性稳定性分析.结果表明,对优质腔来说,与Lugiato等讨论的注入信号为平面波光束及高斯光束(TEM_(00)模)的情况不同,注入光场横向分布具有TEM_(10)模的横式时,环形激光器的输出呈现双稳性.

In this paper we assume that the signal injected into ring cavity laser have a transverse distribution of the TEM10 mode. Using the method of mean field approximation, we obtained the steady state equation and performed linearized stabililty analysis under the one transverse mode resonant condition. The result showed that for the good cavity case the output of laser with a injected signal having a transverse distribution of the TEM10 mode exhibits a bistability, and this is different from the case discussed by Lugiato at al in which the signal injected into ring oavity laser 15 a plane wave beam and a Gaussian beam (TEMqo mode) respectively.
