Theoretical and numerical investigations of parametric transfer via difference frequency generation for indirect midinfrared pulse shaping

We theoretically and numerically investigate indirect mid-infrared pulse shaping via parametric transfer, specifically difference-frequency generation. We define a quantitative measure for the fidelity of parametric transfer, and investigate the effect of material dispersion and process nonlinearity on the parametric transfer. We show that a good fidelity transfer of a broad-bandwidth pulse can be efficiently achieved with a reasonable wavelength tunability, by careful design of the experimental configuration. c © 200
