Abstract : The invention relates to image converters and the like and more particularly to optical upconverters using nonlinear optical materials. The general purpose of this invention is to provide a nonlinear optical upconverter wherein depletion of the pump beam occurs only by the mutual interaction of the pump and signal beams. To attain this, the present invention contemplates a unique optical system having a nonlinear material oriented such that the nonlinear interaction of the two beams occurs only when each of them has a well defined and mutually orthogonal polarization.
