Two-photon holography with continuous-wave lasers.
Two-photon holography with continuous-wave laser sources is accomplished by using carbazole dissolved in a polymethyl methacrylate host matrix as a recording medium. Gating of the holographic sensitivity for 4880-A radiation by irradiation with 3336-A radiation is demonstrated. It is shown that two-photon holographic recording can be accomplished with a wide variety of molecules characterized by four-level spectroscopic systems with cascade excited metastable intermediate levels.
