Volume holographic recording characteristics of an organic medium

Abstract

Volume holographic recording characteristics of camphorquinone in a rigid, acrylic polyester host are presented and related to the observed photoinduced refractive index changes. The dependence of the holographic recording on camphorquinone concentration, temperature, and light intensity is discussed in detail. The holograms are permanent and develop to their final efficiency slowly at room temperature. Heating after exposure can be used to accelerate fixing of the hologram.
