Abstract

Image transfer from the laser excitation (532 nm) to the Stokes (683 nm) is demonstrated and examined in a hydrogen Raman shifter. The frequency conversion of image is based on a nonlinear phenomenon known as stimulated Raman scattering (SRS). The fidelity of the optically converted image is determined under the conditions of varying hydrogen gas pressure (P) and laser input energy (E_in). A dynamic relationship between these experimental variables is observed. A high fidelity image can be generated by tuning these parameters. The transferred image yielded a peak fidelity of 0.7033 at E_in = 7.14 mJ. At this E_in, the fidelity is robust against changes in P.
