Paper Abstract

The present work is devoted to investigation of holographic recording features in medium composed of bipolymer film of DNA, sensitized by organic dyes to He-Ne and YAG-Nd lasers radiation. Two types of holograms formed in the system of dye-DNA by two different modes of recording were studied: (1) transmission holograms recorded by a stationary He-Ne-laser with diffraction efficiency of order 0.02%. (2) Relief-phase holograms (RPH) recorded by a pulse YAG-Nd laser with a diffraction efficiency of order 5%. Despite distinction in efficiency and recording mechanisms the explored holograms are combined by one general property -- they disappear spontaneously during the few hours. The results of the work allow to make conclusions about mechanisms of recording and erasure of holograms, as well as to determine diffusion coefficients in dry film of DNA at a room temperature.
