推导了至少有一维尺寸在发射波长量级的微腔激光器的光输出特性，首次得到了无辐射衰减速率不等于零时速率方程的解析解。结果表明，微腔激光器自发发射到腔模的较高的耦合效。率使激发特性和传统的激光器有很大的不同。在封闭腔，对理想的四能级激光系统，无辐射衰减速率为零时微腔激光器的光输出特性是线性的。当无辐射衰减速率不为零时（实际上往往如此），即使对理想的四能级激光系统的封闭腔，它的光输出特性也不再是线性的。
The optical output characteristics of a microcavity laser with a wavelength of at least one dimension are deduced. For the first time, an analytic solution to the rate equation is obtained when the non-radiative decay rate is not equal to zero. The results show that the higher coupling efficiency of the microcavity laser emitting spontaneously into the cavity mode. The rate of excitation characteristics and the traditional laser are very different. In an enclosed cavity, the optical output characteristics of a microcavity laser are linear for an ideal four-level laser system with zero radiation decay rate of zero. When the rate of non-radiative decay is non-zero (as is often the case), its light output characteristics are no longer linear even for the closed cavity of an ideal four-level laser system.
