"Holographic Plate Efficiency boosted 16 times with new plate material.
Bell Labs scientists have obtained efficiencies as high as 96 per cent with holographic plates using a new material, dichromated gelatin. This efficiency compares with less than six percent for conventional holographic plates.
The new holographic plate material developed at Bell Labs now permits retrieval of information from high density optical memory systems with as little as one-twentieth of the laser beam power required by conventional holographic plates.
Dichromated gelatin plates have been used at Bell Labs for recording high density information and for producing spectroscopic diffraction gratings--used for breaking white light down into its component wavelengths."
