Abstract

In this paper, a scheme is proposed to amplify a seed pulse via non-degenerate four-wave mixing mechanism in plasma. Electron plasma wave excitation and four-wave mixing transmission amplification are examined by two-dimensional particle-in-cell simulations, and the physical factors that affect laser amplification are studied. It is shown that four-wave mixing develops rapidly in dozens of laser cycles and lead to energy transfer between laser beams in the interaction of multiple laser beams and plasma.
