摘要

研究了强x模激光泵浦在预成形抛物等离子体密度分布中的受激拉曼前向散射。激光泵浦激发一个等离子体波和一个/两个电磁边带波。在拉曼前向散射中，参数不稳定性的增长率为泵浦幅值的三分之二次方，随回旋加速器频率的增加而线性增加。

Stimulated Raman Scattering of X-Mode Laser in a Plasma Channel

Stimulated Raman forward scattering (SRFS) of an intense X-mode laser pump in a preformed parabolic plasma density profile is investigated. The laser pump excites a plasma wave and one/two electromagnetic sideband waves. In Raman forward scattering, the growth rate of the parametric instability scales as two-third powers of the pump amplitude and increases linearly with cyclotron frequency.

期刊介绍： Laser and Particle Beams is an international journal which deals with basic physics issues of intense laser and particle beams, and the interaction of these beams with matter. Research on pulse power technology associated with beam generation is also of strong interest. Subjects covered include the physics of high energy densities; non-LTE phenomena; hot dense matter and related atomic, plasma and hydrodynamic physics and astrophysics; intense sources of coherent radiation; high current particle accelerators; beam-wave interaction; and pulsed power technology.
