基于非旋转波近似效应的完美光力诱导透明和放大
LASER & OPTOELECTRONICS PROGRESS(2021)
Abstract
在包含二能级原子系综在内的腔光力学系统中,利用忽略的非旋转波近似效应在不可解边带区域和可解边带区域中,讨论光力诱导透明性质、色散性质和光力诱导放大性质.当驱动光力学腔的驱动光场为红失谐时,可以在可解边带区域和不可解边带区域中分别实现完美光力诱导透明和光力诱导放大的现象.实验结果表明,无论是在可解边带区域还是不可解边带区域中,随着光力学腔的耗散速率的增加,光力诱导透明窗口的半峰全宽会变得很窄,只不过在不可解边带区域中光力诱导透明窗口的半峰全宽远远小于可解边带区域.光力诱导放大的最大值变化情况正好与光力诱导透明窗口的半峰全宽变化情况相反,可解边带区域中光力诱导放大的最大值小于不可解边带区域.
