Abstract
By use of a novel recording technique, 2000 high-resolution image holograms were recorded in a single spectral hole-burning sample at different frequencies and at different values of an applied electric field. We recorded each hologram by sweeping the frequency of a cw laser over a narrow interval while simultaneously changing the hologram phase by 2π. This swept recording technique produces holograms that have increased diffraction efficiency and that exhibit reduced cross talk with respect to conventional frequency-multiplexed holograms.
