Plasma heating by the beat between two light waves
Abstract
Beat-wave heating in an inhomogeneous laser-produced plasma is investigated by considering the beat between two standing light waves. We find that the energy absorbed in this process depends not only on intensities of the incident waves, but also on their coupling coefficient at the beat-wave resonant point. The dependence of this coefficient on the frequency ratio of light waves and scale length of the plasma are calculated.
