Abstract: A phase-matched grating to enhance the second-order diffracted signals generated by forward degenerate fourwave mixing has been proposed and demonstrated for the first time to the authors’ knowledge. Experiments have been performed with a cw Ar:Kr laser at ? – 488 nm, with a linear–nonlinear sandwich of glass slides and Alizarin Yellow-doped films of epoxy resin. Finite-difference simulations have been used to model the process successfully, with finite beam size effects and deviations from an ideal Kerr response of the material taken into account. The possibilities for optical processing applications are assessed in the light of these results.
