摘　　要：We demonstrated the generation and characterization of 9.7 fs,180 J pulses centered at 385 nm via the frequency doubling of few-cycle near-infrared pulses.Both moderate conversion efficiency(9.5%)and broad phase matching bandwidth(20 nm)were achieved by shaping the spectra of the fundamental pulses.The strong intensity dependence of second-order harmonic generation and well controlled material dispersion ensured the inexistence of satellite pulses,which was confirmed by the self-diffraction frequency resolved optical gating measurement.
