Time-Delayed Raman-Enhanced Nondegenerate Four-Wave-MixingExperiments with Incoherence Light in Carbon Disulfide

We report for the first time an experiment of the time-delayed Raman-enhanced non-degenerate four-wave-mixing (RENF WM) with incoherence light in carbon disulfide. We studied the RENFWM signal intensity as a function of the relative the delay τ between two beams which originate from a single broadband laser source. Our results indicate that the temporal behavior of the RENFWM is asymmetric with the maximum of the signal shifted from τ=0. From our experiment results the relaxation time of the Raman mode can be extracted directly.
