We use a Langevin approach to analyze the quantum noise in CoherentAnti-Stokes Raman Spectroscopy (CARS) in several experimental scenarios: withcontinuous wave input fields acting simultaneously and with fast sequentialpulsed lasers where one field scatters off the coherence generated by otherfields; and for interactions within a cavity and in free space. In all thecases, the signal as well as the quantum noise due to spontaneous decay anddecoherence in the medium are shown to be described by the same generalexpression. Our theory in particular shows that for short interaction times,the medium noise is not important and the efficiency is limited only by theintrinsic quantum nature of the photon. We obtain fully analytic results\emph{without} making an adiabatic approximation, the fluctuations of themedium and the fields are self solved consistently.Comment: 12 pages, 1 figur
