Abstract

We theoretically propose soliton-like compression of femtosecond pulses in two-segmented quasi-phase-matching (QPM) grating. By using group-velocity (GV) matching scheme with type-I (o+o:e) second harmonic generation (SHG), we numerically show soliton-like compression of femtosecond pulses with higher quality factor, lower intensity threshold and better spatial-temporal pattern in segmented QPM than periodic structure with the same total crystal length.
