| 摘 要： | 提出了采用双脉冲机理来产生阿秒脉冲的方法.研究发现采用双脉冲不仅可以产生单个的阿秒脉冲，从而突破目前产生阿秒脉冲的驱动源（几个飞秒的超短激光脉冲）的能量限制，而且在相同的峰值强度下，双脉冲能够产生强度更高的阿秒脉冲.

| Abstract: | The scheme of attosecond high-order harmonic generation driven by a two-pulse laser field is proposed. Calculated results show that, not only a single attosecond x-ray pulse can be produced with two pulses, which may break the energy limitation of the few-cycle pulse, but also the intensity is even higher than that generated by a single laser pulse with the same intensity. |

| Keywords: | attosecond pulse two-pulse scheme high-order harmonics |
