论文摘要
通过数值求解色散关系，研究了辐射反作用力在激光驱动的等离子体动力学中的效果，研究了超高血浆中传播的超循环激光脉冲的电子参数不稳定性。重点放在研究激光 - 血浆系统中的不同模式，并在由归一化激光矢量电位和等离子密度跨越的参数图中识别不稳定模式的绝对性和对流性质。指出了对超明式激光 - 血浆实验的影响。
Electronic parametric instabilities of an ultrarelativistic circularly polarized laser pulse propagating in underdense plasmas are studied by numerically solving the dispersion relation which includes the effect of the radiation reaction force in laser-driven plasma dynamics. Emphasis is placed on studying the different modes in the laser-plasma system and identifying the absolute and convective nature of the unstable modes in a parameter map spanned by the normalized laser vector potential and the plasma density. Implications for the ultraintense laser-plasma experiments are pointed out.
