摘要

摘要本文证明了用800 nm为中心的近红外短周期脉冲产生亚40阿秒脉冲是可行的。采用适当的门控技术，可获得50 eV至200 eV以上的超宽带连续谱，并可通过C滤波器对固有阿托啁啾进行补偿，产生持续时间为33 a的隔离阿秒脉冲。根据高次谐波产生的波长标度规律，该方案对开发高通量超短阿秒源具有重要意义。

Chirp compensation for generating ultrashort attosecond pulses with 800-nm few-cycle pulses

Abstract We show that it is feasible to generate sub-40-attosecond pulses with near-infrared few-cycle pulses centered at 800 nm. With proper gating technique, super-broadband continuum spectrum extending from 50 eV to above 200 eV can be obtained, and the intrinsic atto-chirp can be satisfactorily compensated with C filter, producing isolated attosecond pulses with duration of 33 as. According to the wavelength scaling law of high-order harmonic generation, the proposed scheme is of great significance to develop high-flux ultrashort attosecond sources.
