摘　　要：采用二阶劈裂算子算法,通过数值求解强激光场中基态氢原子的含时薛定谔方程,计算了不同的激光脉宽下氢原子的电离率和高次谐波。讨论了激光脉宽对电离率和谐波谱线的影响。The ionization probability and high-order harmonic spectrum of hydrogen atom under different laser pulse are computed by solving the time-dependent Schrodinger equation of hydrogen atom in a intense laser field, in which an algorithm of split-operator is quoted. The effects of pulse width on ionization probability and high-order harmonics are discussed.
