title: Enhancement of the two-wave-mixing gain in a stack of thin nonlinear media by use of the Talbot effect.
abstract: We show that the Talbot effect can be used to increase the gain of two-wave mixing in a stack of thin nonlinear media. We demonstrate that a large gain enhancement is achieved for a few nonlinear elements, provided that they are placed at distances that satisfy Talbot recurrences.
