title: Holographic recording on electron beam colored sodium chloride crystals.
abstract: Color centers produced in sodium chloride crystals by electron beam bombardment have been used for holographic recording. The holograms were constructed with the 4762-A radiation of a krypton ion laser. Reconstruction was demonstrated with both the 4762-A and 5682-A radiation of the same laser. The possibility of reconstruction in the M band, centered at 7350 A, was postulated but was not demonstrated. It was shown that the electron beam coloring technique converts complex R and M centers formed by bleaching back to F centers, making the crystals reusable. The efficiency of the electron beam coloring process and the penetration depth of the color centers as a function of the accelerating voltage were determined.
