Dynamic selective reflection from a low-density atomic vapor

The dynamics of selective reflection when atomic vapor density is modulated are studied. In our theoretical work, we found a new type of light emission in selectively reflected light, which differs from that of ordinary selective reflection. It is understood to be backscattering from a moving dynami...

Description
Summary:The dynamics of selective reflection when atomic vapor density is modulated are studied. In our theoretical work, we found a new type of light emission in selectively reflected light, which differs from that of ordinary selective reflection. It is understood to be backscattering from a moving dynamic grating created in density-modulated atomic vapor. Experimentally, the dynamics of the selective reflection are studied by analyzing the intensity spectrum of the reflected light intensity.
