초록
With dichromated bleacher and alcohol drying, over effi. of 81% has been achieved for holographic gratings. It is recorded by two plane waves at 632.8 nm in Agfa 8E75 film. Swollen emulsion and rapid dehydration make a strong modulation. The model works well close to the Bragg condition. It is suggested modified parameters of coupled-wave theory which have good agreement with experimental results.
