消逝波增益耦合球形微腔中的受激拉曼散射

Stimulated Raman Scattering from a Micro-Cavity with Raman Gain Coupled from the Evanescent Field

针对球形微腔能否将腔外介质的拉曼增益耦合到腔内,并在微腔回音壁模式的支持下形成腔外介质的受激拉曼辐射的问题,通过石英球腔在纯水中的受激拉曼散射实验,首次观察到水的拉曼增益确实可以通过消逝场耦合进入球腔,并在腔内形成拉曼光的受激辐射放大.

The research discusses the possibility to couple the Raman gain, which surrounds a spherical mieroeavity, into the Whispering Gallery Modes of the cavity and forms the stimulated Raman scattering of surrounding medium. By inserting a spherical quartz micro - cavity into pure water, the research has proved for the first time the stimulated Raman scattering of water from quartz cavity, of which Raman gain is coupled into the cavity by an evanescent field.
