A Theoretical and Experimental Study on The Application of Stimulated Raman Spectroscopy.

An analysis of the stimulated Raman scattering process has been carried out for three variational techniques of stimulated Raman spectroscopy SRS using low power CW lasers and synchronous detection techniques. The three variational techniques of SRS examined are direct SRS, Raman-Induced Kerr Effect RIKES and Optically Heterodyned RIKES OHD RIKES. In this analysis the Raman scattered signals for all three variational techniques were derived using Maxwells equations for both amplitude and phase modulation techniques. The noise contributions for each technique were also examined. It was found that the main source of noise for each technique was due to probe laser intensity fluctuations.
