An unexpected two-beam coupling energy exchange has been observed in Bi 12 SiO 20
without normal (electro-optic) photorefractive effects, using circularly polarized light and a …

Abstract Photorefractive gain in Bi 12 SiO 20 (BSO) crystal was studied using a two-wave
mixing configuration. It was clear that the gain was strongly dependent on the incident plane …

We demonstrate the possibility of collinear Bragg diffraction in photorefractive Bi_12SiO_20
(BSO) crystals of two incident writing and readout beams of different wavelengths. Two …

The amplification of the input signal beam in two-wave mixing experiments with
photorefractive Bi 12 SiO 20 crystals is achieved when an additional phase shift is …

Multiple optical interference patterns generate phase gratings in Bi_12SiO_20 as a result of
the photorefractive effect. Because of the nonlinear response of the space-charge field to the …
