Time-resolved Brillouin spectra in a CO2 laser plasma interaction
Abstract
Kerr cell techniques have been used to obtain spectra at 10.6 μm of the radiation backscattered from a CO2 laser plasma interaction. The spectrum is strongly red-shifted at high energies, with spectral modulation. These aspects of the backscattering suggest that the scattering is occurring from ion quasimodes produced by the strong coupling of the laser to the plasma.
