Measurements of the Microscopic Properties Contributing to Photorefraction in Barium Titanate

Abstract

The photorefractive effect is a nonlinear optical phenomena that can produce phase conjugate (complex conjugate) reflection of visible light in a crystalline solid. Very little is known about the microscopic origin of photorefraction; consequently this thesis investigates the following microscopic parameters of barium titante (Barium Titante): the quantum efficiency, charge transport length and the carrier generation rate both theoretically and experimentally. BaTiO3 was chosen because it is a highly nonlinear crystal with large electrooptic coefficients and therefore, is a very efficient photorefractive material. Keywords: Phase Conjugation, Barium Titanate; Photorefraction; Crystals, Lasers.
