Abstract
A simple technique to generate holographic optical elements with diffraction-limited performance at a wavelength different from the construction wavelength has been developed. The method consists of specifying the desired grating performance at the operating wavelength, selecting one construction beam, and utilizing a ray trace program to compute the aberrated construction beam required to create the hologram. A lens capable of focusing this aberrated beam to a point may then be designed using ACCOS-5. A point source used with this lens thus serves to generate the second required construction beam. A sample design which may be used to construct with 0.4579-μm light a grating to operate at 2.8 µm is presented.
