Dj. Webb et al., VERIFICATION OF THE STANDARD MODEL OF THE PHOTOREFRACTIVE NONLINEARITY IN BSO CRYSTALS, Optics communications, 108(1-3), 1994, pp. 31-36
On the basis of the standard model for the photorefractive nonlinearit
y we investigate whether a systematic description of the dependence of
two-beam energy exchange on beam polarization and grating vector K is
possible. Our result is that there is good agreement between theory a
nd experiment with respect to the polarization properties and semi-qua
ntitative agreement with respect to the K-dependence of the energy exc
hange.
