Two-photon holographic recording with continuous-wave lasers in the 750-1100-nm range

Two-photon holographic recording with cw laser sources in the 750-1100-nm spectral range is accomplished using recording materials consisting of an α-diketone dissolved in a poly-α-cyanoacrylate host. Gating of the holographic sensitivity by irradiation with incoherent UV radiation is demonstrated. Hologram diffraction efficiencies as large as 10% are achieved. © 1982 Optical Society of America.
