摘　　要：研究发现，在超强激光作用下电子运动的相对论效应可导致高农谐波辐射。采用单电子模型计算分析了不同偏振激光作用下的高次谐波发射，表明圆偏振激光较线偏振激光更有利于高次谐波产生。It is discovered that driven by the super strong laser field, the oscillation of electrons, due to their relativistic motion, will generate harmonic emission. The characteristics of the harmonies are analyzed with a single electron model in the case of different laser field polarization. It is found that the harmonic emission is more effective in the case of circular polarization than linear polarization.
