摘　　要：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.
