Abstract
Excitation of electron plasma waves by the mixing of two microwave beams is studied in a laboratory plasma. The first experimental observation of pump wave depletion is presented. The numerical calculations, based on one-dimensional model, describing space-time evolution of eight interacting waves, are in good agreement with experimental data. Estimation of the depletion on the basis of conservation laws is also discussed.
