Holographic recording in thermoplastic at 1.15 μm

Abstract
Holograms have been recorded on an photoconductor‐thermoplastic device at 1.15 μm. Diffraction efficiencies of 1–5% were obtained with exposures of 400–800 mJ/cm2. Holograms were formed in situ with rapid processing and at spatial frequencies as high as 1000 lines/mm.
