The applicability of the technique of two-photon four-level photochemistry for the production of near-IR holograms is critically evaluated. Although the current best system (biacetyl in a polycyaneacrylate matrix) has low recording sensitivity, several applications of the material have been demonstrated. Hologram efficiencies of up to 70% recorded at 752 nm are shown. Recording of extended holographic images and production of holographic optical elements are demonstrated. Finally, we have recorded holograms directly with GaAlAs diode lasers. © 1982 Optical Society of America.
