Abstract
Spectra of 90° scattered light from underdense plasmas evidence a line close to the second harmonic of laser frequency, whose red shift is consistent with frequency sum between incident laser light and Brillouin backscattered light. Time-resolved spectra give information on the dynamics of the process.Keywords
