Abstract

Hollow-core photonic-crystal fibers are shown to substantially enhance four-wave mixing (FWM) of laser pulses in a gas filling the fiber core. Picosecond pulses of Nd:YAG fundamental radiation and its second harmonic are used to generate a signal at the frequency of the third harmonic by the FWM process 3⍵=2⍵+2⍵-⍵ . The efficiency achieved for this process in a 9-cm-long, 13-mu;m -hollow-core-diameter photonic-crystal fiber, designed to simultaneously transmit a two-color pump and the FWM signal, is shown to be ~800 times higher than the maximum FWM efficiency attainable with the same laser pulses in the tight-focusing regime.
