摘要
在超短超强激光与等离子体相互作用的过程中 ,等离子体中的一部分电子通过各种机制吸收能量转变成为高能的超热电子 .它们不仅是惯性约束核聚变“快点火”过程中的能量载体 ,对激光脉冲在等离子体中的传输、能量沉积、转化等一系列过程也都发挥着重要的作用 .
High-energy hot electrons are generated during the interaction of ultra-intense laser pulses with plasmas, which are not only the energy carriers in “fast ignition” of inertial confinement fusion, but also play important roles in the processes of energy transportation, deposition and conversion. The main mechanisms of hot-electron generation are reviewed and the effects that influence the collimation and propagation during the interaction of ultra-intense laser with plasmas are discussed.
