Paper Abstract

Recently it has been observed an effect of prolonged memory of holographic recording without applied electric field in photorefractive Bi12Ti020 (13T0) crystals at room temperatures. High frequency holographic diffraction gratings (with K = 2 71- / Λ - 3.104 mm-1 , where A is the grating period) are recorded in BTO with He-Ne laser. The homogeneous interfering beams are incident on two mutually perpendicular crystal surfaces. This is the orthogonal recording geometry2.
