High power laser Raman scattering from a rarefied plasma

In this paper, the intensity of the Raman scattering is calculated. The rel ation between the intensity of the Raman scattering and the plasma wave is obtained. The theoretical results show that the intensity of the Raman scat tering is obviously dependent on the plasma density. The evolutions of the Raman scattering and the plasma wave are closely correlated with the scatte ring frequency Generally, the incident laser has no obvious effects on the plasma wave and only at extremely strong laser incidence, it will result in obvious changes in the amplitude of the plasma wave.
