Paper Abstract

Nongelatin dichromated holographic film (NGD) is a new holographic recording material. The holograms recorded on this material have better environmental stability, higher diffraction efficiency, stronger real time effect, etc. In this paper, an experimental study to ascertain the influence of two electron donors, namely N,N--dimethylformamide (DMF) and dimethylsulfoxide (DMSO), on the real time diffraction efficiency (RTDE) of NGD holograms is carried out. The presence of electron donors not only improves the sensitivity but also enhances the real time effect greatly. The RTDE of above 60% at +/- 1 orders of NGD plane transmission gratings is achieved by introducing electron donors.
