Abstract
Stimulated Brillouin scattering with both pump and Stokes beams in resonance with whispering gallery modes of an ultrahigh calcium fluoride resonator is demonstrated for the first time. The resonator is pumped with 1064 nm light and has 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.
