title: Infrared recording of transient and permanent interference gratings with commercial plastics.
abstract: Two commercial plastics have been used to record infrared interference patterns when a CO(2) laser is used as a light source. Recording of transient and permanent interference gratings with different spatial frequencies was carried out. The diffraction efficiency for red light as a function of time for different exposure times is shown; maximum diffraction efficiencies attained were of the order of 30%. The possibility of using one of these plastics as an optical switch is shown.
