The spatial spectrum of angular phase matching for photorefractive devices that use orthogonally polarized reading and writing beams may be enhanced if the images are recorded at angles where the ordinary and extraordinary cross sections of the index ellipsoid have equal curvatures. Applications include holographic storage, phased-array radar processors, and achromatic photorefractive devices. We show that for holographic recording in lithium niobate the maximum wavelength separation between writing and reading beams is approximately 50 nm for writing at 500 nm.
