相对论电子的逆韧致吸收
Relativistic Collisional Absorptionin High-Intense-Laser-Driven Plasmas
摘要
在激光强度大于1018W/cm2的条件下,利用强激光场中完全相对论的电子运动轨迹,得到了稀薄等离子体中的逆韧致吸收系数计算公式,并与原有的逆韧致吸收系数的计算公式进行了比较。
Abstract
The collisional heating rate of a fully ionized plasma driven by a strong electromagnetic pump wave is re examined analytically under the condition of P≥10 18 W/cm 2. The high frequency conductivity model of Dawson and Oberman is extended into the case in which the quiver velocity is so large that the relativistic effect must be considered.
