Intensity redistribution in a thin photorefractive crystal caused by strong fanning effect and internal reflections

Intensity redistribution in a thin photorefractive crystal caused by strong fanning effect and internal reflections. Kamshilin, Alexei A.; Raita, Erik; Khomenko, A. V. (Department PHysics, University Joensuu, Joensuu SF-80101, Finland).Some commonly used reagents like 12441-73-5 is used in this experiment. Journal of the Optical Society of America B: Optical Physics, 13(11), 2536-2543 (English) 1996 Optical Society of America. CODEN: JOBPDE. ISSN: 0740-3224. DOCUMENT TYPE: Journal CA Section: 73 (Optical, Electron, and Mass Spectroscopy and Other Related Properties) Propagation of the light beam in a thin photorefractive crystal with the diffusion-type mechanism of nonlinearity was studied both exptl. and theor. Total internal reflections of fanned beams from the crystal's side surfaces and their coupling with the pump beam result in the light-intensity redistribution and in the generation of the photorefractive surface wave. The authors propose a theor. model of the intensity redistribution that considers the light-energy flow from the pump beam to the fanning beam and backward after the fanning beam reflection. A numerical simulation shows that the total internal reflection off the surface, toward which the flow of the light energy is directed, is responsible for the light-energy self-concn. .

Polarization properties of fanning light in fiberlike bismuth titanium oxide crystals

Polarization properties of fanning light in fiberlike bismuth titanium oxide crystals. Raita, Erik; Kamshilin, Alexei A.; Jaaskelainen, Timo (Department of Physics, Vaisala Laboratory, University of Joensuu, Joensuu SF-80101, Finland). Optics Letters, 21(23), 1897-1899 (English) 1996 Optical Society of America. CODEN: OPLEDP. ISSN: 0146-9592.Several reagents such as 12441-73-5 is used here. DOCUMENT TYPE: Journal CA Section: 73 (Optical, Electron, and Mass Spectroscopy and Other Related Properties) The authors demonstrated that the fanning light emerging from an optically active fiberlike bismuth titanium oxide (Bi12TiO20) crystal was linearly polarized either parallel to the applied elec.-field vector or perpendicular to it, independently of the external a.c. elec. field, the crystal length, and the pump beam polarization state. The authors also showed that a photorefractive surface wave can be generated at the opposite crystal sides, depending on the pump beam polarization. .
