摘要
The effects of field correlation on Raman-enhanced nondegenerate four-wave mixing(REN-FWM)have been investigated by examining the RENFWM spectra as a function of time delay between two beams.An enhancement of the ratio between the resonant and nonresonant REN-FWM signal intensities was found as the time delay was increased when the laser had broadband linewidth.
