摘要 采用数值方法研究静电场和不同的激光脉冲对氢原子的电离率和高次谐波的影响。结果表明脉冲形状和电离率之间有着确定的关系 ,电离率反过来又影响了谐波谱的性质 ;另外 ,随着所加的静电场强度的增大 ,电离率呈上升的趋势 。 We study the effects of pulse shape and static electric field on ionization and high order harmonic generation (HHG) of a one dimensional model hydrogen atom. The series of results indicate that there is a certain relationship between the ionization probability and the pulse shape, which in turn influences the character of HHG. The ionization probability increases as the additional field intensity is increased. The HHG spectrum exhibits a double platea structure when the intensity of the electric field is suitable.
