Abstract:

The addition of a dye to a dichromated gelatin system extends the spectral sensitivity of the system throughout the visible and near infrared spectral regions. The dyes found to be effective as the sensitizer additive are those from the thiazine and triphenylmethane chemical families. The dye sensitized dichromated gelatin of this invention is capable of producing permanent, thick, phase holograms of high diffraction efficiency, good optical quality, and large refractive index change in the red spectral region.
