Abstract

In terms of energy conservation and vector matching relations, the dynamic process of the second harmonic emission from a laser plasma has been analyzed in this article for the first time. Then, considering the Langmuir wave spectrum which reflects the second harmonic spectrum, we derive the kinetic equation of the Langmuir wave. After a numerical Fourier analysis, the spectrum profiles are obtained, which coincide well with the experiments.
