Stimulated Scattering of Laser Radiation in an Aqueous Suspension of Glass Microspheres
Tóm tắt
The excitation of stimulated scattering of laser radiation at several equidistant frequencies is observed in an aqueous suspension of hollow glass microspheres. The scattering spectrum is frequency-asymmetric. No stimulated Brillouin scattering, accompanying nonlinear processes in condensed media excited by narrowband laser pulses on the order of tens of nanoseconds, is detected. The observed features are interpreted in terms of stimulated scattering mediated by the whispering-gallery modes of glass microspheres.
