首次在碲化镉晶体中观察到了由反转镜和普通平面镜构成的谐振腔和无反转镜的谐振腔中的频率简并参量激光。计算了考虑泵浦波饱和时的激射过程的能量特性。当抽运率增加到阈值以上时，观察到输出辐射强度的非单调变化，确定了与禁戒激光相对应的抽运率间隔，并发现了双稳态行为的区域。
Frequency-degenerate parametric lasing was observed for the first time in a cadmium telluride crystal both in a resonator formed by reversing and ordinary plane mirrors and in a resonator without such mirrors. A calculation was made of the energy characteristics of the lasing process allowing for saturation of the pump waves. A nonmonotonic variation of the intensity of the output radiation was observed on increase in the pumping rate above the threshold value, the intervals of pumping rates corresponding to forbidden lasing were determined, and the regions of bistable behavior were found.
