Stimulated Brillouin scattering with both pump and Stokes beams in resonance with whispering gallery modes of an ultrahigh Q calcium fluoride resonator is demonstrated for the first time. The resonator is pumped with 1064 nm light and has 3 muW Brillouin lasing threshold. The scattering is observed due to the unique morphology of the resonator reducing the phase mismatch between the optical modes and the hypersound wave.
首次展示了在超高Q值氟化钙谐振器的回音壁模式中共振的泵浦光束和斯托克斯光束的受激布里渊散射。该谐振器用1064nm的光泵浦，布里渊激光阈值为3μW。由于谐振器独特的形态减少了光学模式与超声波之间的相位失配，因此观察到了散射现象。
