Characterization of transmission volume holographic gratings recorded in Slavich PFG04 dichromated gelatin plates

摘要

We characterize Slavich PFG-04 dichromated gelatin plates to make transmission volume holographic elements recorded with a 532 nm laser source, obtaining high efficiency gratings with a high signal to noise ratio. The linear dynamic range of the material is studied by measuring the efficiency of multiplexed gratings. Results obtained are applied to the recording of holographic elements with high efficiency when they are illuminated with a 800 nm light source.
