【摘要】 提出采用附加谐波脉冲来提高阿秒脉冲的强度。研究表明,与单一强短激光脉冲(脉冲宽度只有几个光学周期的超短脉冲)辐照原子获得孤立的阿秒脉冲相比,通过附加谐波脉冲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。更多还原

【Abstract】 In the paper,the scheme of the attosecond(asec) pulse enhancement by the addition of a harmonic pulse is proposed.Our numerical results show that,this scheme can also produce an isolated asec pulse,furthermore the intensity of which is prominently enhanced,compared with the asec pulse generation of a single laser pulse(duration of the pulse is several cycles) irradiating atoms.更多还原
