| 摘 要： | 采用组合激光脉冲(800 nm/9.4 fs 24 nm/1 fs)辐照联合两原子体系产生高次谐波,获得了单一的X-射线阿秒脉冲.我们发现,当固定钛宝石激光的峰值强度并改变高频谐波脉冲的峰值强度Ih时,存在一个优选的Ih范围,在该范围内相应的阿秒脉冲最优化,即强度达到最强,对此,本文从受激复合的角度给出了合理解释. |

| Abstract: | In this paper the single X-ray attosecond pulse generation is obtained from two-atom system exposed to the combined laser pulse(800 nm/9.4 fs 24 nm/1 fs).Furthermore,when we change the peak intensity Ih of the high-frequency pulse and keep the intensity of the Ti:sapphire pulse unchanged,we find that there is a range of Ih where the intensity of the asec pulse is the most intense,and we present reasonable explanations from the stimulated property of the recombination. |
| Keywords: | high-order harmonic generation combined laser pulse twoatom system X-ray attosecond pulse |
