Abstract

We report for the first time an experiment of the time-delayed Raman-enhanced non-degenerate four-wave-mixing (RENFWM) with incoherence light in carbon disulfide. We studied the RENFWM signal intensity as a function of the relative time 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 experimental results the relaxation time of the Raman mode can be extracted directly.
