摘要:

从多粒子系统量子力学理论出发,应用电子与多光子集团非弹性碰撞模型,研究了固体中形成的激光等离子体中的电子与入射光发生多光子非线性Compton散射下,散射光与入射光、电子振荡辐射波、离子的长光学横波的高频支形成的耦合等离子体波前的传输特性。结果表明,固体中激光等离子体电磁耦合声子的传播速度随磁场强度的增强、电子屏蔽作用的减弱及等离子体振荡频率的减小而变大,而散射光却使电磁耦合声子传播速度的这种增长效应降低,它随时间的增加也较缓慢地降低。

Abstract:

Using the model of inelastic scattering between electron and photon-groups, we have studied in the frame of quantum mechanics the transmission characteristics of the kinematics of the coupling laser-plasma wave, this is formed by the scattered light, the incident light, the electron vibration radiation wave and the high frequency branch of ILOTW (ion long optics transverse wave) in solid under nonlinear Compton scattering. The results show that the transmission velocity of the electromagnetism coupling phonon in the laser-plasma in the sold is raised along with the increase of the magnetic field intensity,the decrease of the electron screening action and the decrease of the plasma vibration frequency. But this increase of transmission velocity is resisted by the scattering light, and will be slowly reduced.

Key words: Plasma, Quasi-Mach number, Burst, Blast wave, Multi-photon nonlinear Compton scattering
