Chirped Four-wave mixing in the largely normal dispersion regime from femtosecond Pulse-pumped photonic crystal fiber


Journal Article

A four-wave mixing process of 4700 cm-1 Stokes-shift is stimulated by pumping a 20-cm commercial large-mode-area photonic crystal fiber with amplified Ti:sapphire femtosecond pulses. The phase-matching condition is realized through an intermodal scheme which promotes the process in the largely normal dispersion regime of the fiber. The walk-off effect of the interacting pulses is minimized by introducing an initial chirp to the pump pulses. Conversion efficiency over 7% from near-infrared pump input to visible anti-Stokes signal can be achieved. © 2009 SPIE.
