Collinear Bragg diffraction in photorefractive Bi12SiO20

Abstract

We demonstrate the possibility of collinear Bragg diffraction in photorefractive Bi12SiO20 (BSO) crystals of two incident writing and readout beams of different wavelengths. Two grating wave vectors K1 and K2 are created by interference of independent and collinear beams at wavelengths λ1 and λ2. In the photorefractive medium the nonlinearities of the photoinduced space-charge field generate the new grating wave vectors KNL = mK1 ± nK2. Bragg diffraction is thus achieved at a readout wavelength λR such as 1/λR = (m1) ± (n2). The proposed method permits quasi-nondestructive readout of a phase-volume grating in BSO at λR = 840 nm (semiconductor laser) while recording is done by interference of two incident and collinear beams at λ1 = 632.8 (He–Ne laser) and λ2 = 514.5 (Ar laser).
