Abstract

THE techniques of coherent Raman spectroscopy are revolutionising the applications and scope of Raman spectroscopy. Particularly important aspects are: very high resolution spectroscopy (the Doppler width being proportional to the Raman shift of the band under study); nanosecond (and sub-nanosecond) spectroscopy, where the resolution obtained may be limited by the Fourier transform of the experimental time scale; discrimination against luminescence from the sample (whether laser induced or not). We discuss here coherent anti-Stokes Raman spectroscopy (CARS) at low frequency shifts.
