Abstract

A technique for obtaining sensitive, highly reproducible, time-resolved inverse Raman measurements is reported. Experimental results are presented for the nitrogen vibrational Q branch at a pressure of 10 atm. For these measurements the signal, normalized to the pump-laser energy, exhibits fluctuations of 1.4% (rms) about the average of 500 measurements; these deviations are within a factor of 2 of the quantum noise limit.
