Observation of coherent anti-Stokes Raman scattering in the phase-mismatched direction

摘要

We have experimentally demonstrated coherent anti-Stokes Raman scattering in both forward and backward directions from thin samples of dipicolinic acid crystalline. The signal observed in the backscattered, phased-mismatched direction is 3 orders of magnitude stronger than would be expected without scattering from the crystal's inhomogeneities. We present a theoretical explanation of these results, based on the theory of random diffraction gratings and discuss possible applications. (C) 2005 Optical Society of America.
