Numerical analysis of image wavelength down conversion using finite difference (FD) method

Abstract

Image transfer from the laser wavelength to another through stimulated Raman scattering is numerically studied. The SRS wave equations are solved using two-dimensional finite difference (FD) method. The stimulated down converted images are found to be highly dependent on the laser input power and Raman gain. With FD technique, the converted images are found to be in good correspondence with the laser image.
