从理论上考虑了当光子平均自由程远小于散射区的尺寸时，具有负共振吸收的散射介质产生光。这种量子发生器中的负反馈是不共振的。确定了量子发生器的产生阈值，并考虑了稳态条件的建立和辐射谱的变窄等动力学问题。在产生条件下，由于散射粒子的波动运动，发现了辐射谱的极限宽度。讨论了这种量子发生器作为稳定频率光振荡源的使用。
Generation of light by a scattering medium with negative resonance absorption is considered theoretically for the case when the photon mean free path is much smaller than the dimensions of the scattering region. The negative feedback in such a quantum generator is not resonant. The generation threshold of the quantum generator is determined and the dynamics of the establishment of stationary conditions and narrowing of the radiation spectrum are considered. The limiting width of the radiation spectrum under generation conditions, due to fluctuation motion of the scattering particles, is found. The use of such a quantum generator as a source of stable frequency light oscillations is discussed.
