We investigated experimentally the transformation of the spectrum and the amplitudes of neodymium-laser radiation reflected from a plasma at intensities 10l5-3xl016 W/cm2. Rather narrow regions of plasma luminosity were observed at the frequencies 2ω0 and 3ω0/2. Various mechanisms that can be responsible for the observed effects are considered.
