Research on Imaging Properties of Optical Parametric Upconverter
Abstract
The imaging properties of parametric upconversion have been investigated analytically and experimentally for the case of monochromatic object waves, and photographs of upconverted 10.6 micrometers images obtained. Using geometric optics an expression was derived relating the locations of the object, the pump and the upconverted image. The effect of higher order factors such as crystal birefringence, phase mismatch, and pump wave divergence were considered qualitatively. The analysis was then extended by applying the techniques of physical optics. Using Fourier transformer formalism an expression was derived relating the angular spectrum of the sum-frequency field with that of the object and pump fields. Two cases were examined in detail, one using a plane wave pump and the other with a Gaussian distributed pump beam.
