Abstract
We specified 406 mm diameter off axis powered HOEs to operate at 1.06 microns and for trials at 670 nm, then looked for ways to construct them at 488 nm. We were able to write holographic surfaces directly in Zemax, then play back other wavelengths through them to display the aberrations that needed to be canceled. Zemax had easy entry and optimization routines that allowed us to do cut and try construction variations on screen rather than on the table. We designed construction set ups using only off the shelf lenses and mirrors and were able then to fabricate the HOEs with only small incremental improvements being made on the table. The computed spot sizes were less than .5 mm diameter and constructed holographic optics were on Bragg with outputs as small as .5 mm and high efficiencies.
