摘要 Starting with the nonlinear equations for describing intense laser plasma interaction,without the supposition of tenuous plasma,weak relativity and a priori assumption φ<<1+φ2,the slowly varying part and rapidly varying part of scalar potential φ,and the ratio of third harmonic to pumping laser a3/a1 in plasmas pumped by intense laser (≥1018W/cm2) are obtained.And the plasma and laser parameters favorable for generating harmonic are discussed.
