Abstract

By eliminating the group-velocity mismatch and enhancing the group-velocity dispersion via pulse-front tilting, we obtained the formation of temporal solitary waves in phase-mismatched second-harmonic generation. Experimental and numerical results match well in a wide range of intensities and $Δ k$ 's. In a 7 mm BBO crystal, 58 fs, 527 nm pulses are obtained starting from 200 fs pump, at the same wavelength.
