| 摘 要： | 通过利用短时指数传播子的对称分割和快速傅里叶变换，数值求解一维含时薛定谔方程，研究了一维多原子分子离子在超强脉冲强激光场中的增强电离(EI)行为，给出了激光强度和频率对增强电离的影响.计算表明随着激光频率的增加，增强电离的临界键长变小，电离概率 也减小；随着激光强度的增加，电离概率增加，当强度增加到一定值时，就不再出现增强电离现象.

| Abstract: | The enhanced ionization(EI) behavior of multiatomic molecular ions is studied in intense laser fields by the numerical solution of time\|dependent Schrodinger equation with the symmetrical splitting of the short\|time exponential propagator and fast fourier transformation(FFT).The influence of the intensity and the frequency of the laser on EI is given.With the laser frequency increasing,the criticla value of bond length for EI decreases and the ionization probability decreases too.The ionization probability increases with increasing laser intensity.The EI disappeares when the intensity reaches a certain value. |
