摘要

研究了在无碰撞磁化等离子体中叠加在强高斯激光上的径向对称纹波的生长。采用WKB近似和近轴射线近似计算了主波束和波纹的波动方程。数值计算结果表明,激光束的相对功率和脉动的动力学特性受到激光束位置和相位角等参数的影响。研究了纹波的增长对上杂波激励的影响。

Growth of high power laser ripple in plasma and its effects on upper hybrid wave excitation: Relativistic effects
The growth of a radially symmetric ripple superimposed on a single intense Gaussian laser beam in a collisionless magnetized plasma is investigated. WKB and Paraxial ray approximations are used to calculate wave equation for the main beam and the ripple. Numerical results show that the relativistic power of laser beam, the dynamics of ripple gets affected by its position and phase angle as well as some other parameters. The effect of growth of ripple on excitation of upper hybrid wave is also studied.
