Abstract
Two intense electromagnetic waves interact strongly where the local plasma frequency equals their difference frequency, resulting in an irreversible transfer of action from the higher-frequency wave to the lower-frequency wave. The amount of transfer depends only on the intensities and the density scale length. Successive transfers among a set of waves may produce efficient plasma heating.Keywords
