| 摘 要： | 采用强短激光脉冲辐照叠加态原子提高孤立阿秒脉冲的强度。数值研究表明，与强短脉冲
(脉冲宽度只有几个光学周期的超短脉冲）辐照基态原子获得孤立阿秒脉冲相比，采用叠加
态原子的方案不仅同样可以获得孤立的阿秒脉冲，而且阿秒脉冲的强度得到显著增强。

| Abstract: | The scheme of the attosecond (asec) pulse intensity enhancement by an intense short laser pulse (duration of the pulse is several cycles) irradiating an atom with coherent superposition state is proposed. Our numerical results show that, this scheme also could generate an isolated asec pulse, furthermore the intensity of which is prominently enhanced, compared with the asec pulse generation of an intense short laser pulse irradiating an atom with ground state. |

| Keywords: | high-order harmonic generation intense short laser pulse attosecond pulse |
