| 摘 要： | 由于部分离化激光等离子体中存在束缚电子，它可显著改变其参量不稳定性。本文分析了部分离化激光等离子体的受激喇曼散射的非线性色散关系，计算了钕玻璃倍频和三倍频激光受激喇曼散射的增长率，结果表明，前向受激喇曼散射显著增强，后向受激喇曼散射影响不大。

| 关 键 词： | 部分离化激光等离子体，增长率，受激喇曼散射。 |

| Abstract: | In a partially ionized plasma the presence of bound electrons can significantly alter the laser plasma parametric instabilities. In this paper the nonlinear dispersion relation in intense laser partially ionized plasma is analysed. The growth rate of the forward stimulated Raman scattering
is significantly enhanced by the presence of bound electrons; on the other hand the backward stimulated Raman scattering is unaffected. |

| Keywords: | intense laser partially ionized plasma growth rate forward stimulated Raman scattering |
