| 摘 要： | 研究了强激光与具有初始速度分布的等离子体作用产生的高次谐波。结果表明，对于Maxwell速度分布的等离子体，由于电子初始时刻的无规则热运动，在一定程度上抹平了辐射功率在谐波谱上的分布，使得高次谐波的辐射增强，低次谐波的辐射有所减弱，有利于高次谐波的产生。

| Abstract: | High-order harmonic generation by relativistic lasers in plasmas with initial velocity distribution has been studied. It is shown that, different from previous models, because of the random thermal motion of electrons, the initially Maxwellian distributed plasma will make the harmonic spectrum more smooth, i.e., it increases the higher-order harmonic power but decreases the lower-order harmonic power. This effect is beneficial for the generation of higher order harmonics． |
