Abstract

The properties of a high-efficiency lens, fabricated in bleached photographic emulsion, are discussed. A symmetric off-axis configuration is adopted, and approximately uniform dielectric-constant modulation is achieved. The lens is tested using a probe beam of small diameter. Experimental results are presented for replay under on- and off-Bragg conditions, both in air and under index-matched conditions. 59±3% efficiency is achieved across the lens aperture. Variations in efficiency are attributed to rotation of fringe planes, and results are compared with local one-dimensional theory.
