The characteristics of diffraction gratings, fabricated using Slavich PFG-01 plates as a holographic recording material, were investigated using various bleach techniques. The changes in diffraction efficiencies, under given development conditions, resulting from the use of a new reversal bleach and a new fixation free rehalogenating bleach are investigated. From the experimental results, it was found that the diffraction efficiencies are influenced by the composition of the developer, the reversal bleach and the fixation free rehalogenating bleach. In this study, the highest values of the maximum diffraction efficiency was obtained when PFG-01 plates were developed in AAC developers contained with l-ascorbic acid 20 g/L and sodium carbonate 60 g/L, processed by a reversal bleach, as high as 89.0%. Moreover, the maximum diffraction efficiency of 82.1% was obtained when PFG-01 plates were processed by a fixation free rehalogenating bleach. In addition, higher diffraction efficiencies are yielded in the case of the revesal bleach than in the case of the fixation free rehalogenating bleach.
