Abstract

Nonlinear optical effects may provide a way to perform all-optical parallel processing of images. Here, we investigate the possibilities offered by Type II intracavity second harmonic generation. We show that injecting an image in one polarization and a homogeneous field in the other, we obtain, according to the value of the latter, either the frequency and polarization transfer of the image or the possibility to enhance its contrast.
