We introduce a method to determine the electrooptic coefficient r(33) and the, effective density of, the photorefractive centers N-eff from the angular distribution of the scattered light. The temperature dependeme of these two parameters is discussed with respect to the phase-transition behavior. (C) 2003 Elsevier Science B.V. All rights reserved. |
