Abstract

The nature of plasma waves which are resonantly excited when two laser beams beat in a rippled-density plasma is explored both theoretically and experimentally. A theoretical model is presented which, for commonly encountered experimental parameters, predicts rapid saturation of the highphase-velocity beat wave at an amplitude below that expected for relativistic detuning. Results of experimental studies of this process are presented.
