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.
