Nonequilibrium screening of the photorefractive effect

DD Nolte, DH Olson, AM Glass - Physical review letters, 1989 - APS
The nonequilibrium occupation of multiple defect states in inhomogeneously illuminated
crystals is demonstrated to have dramatic and previously unexpected consequences for the …

Kinetics of photorefractive recording for circular light beams

M Kösters, B Sturman, D Haertle, K Buse - Optics letters, 2009 - opg.optica.org
We show, theoretically and experimentally, that the buildup of the space-charge field in
photorefractive crystals is far from monoexponential for circular light beams. This is a …
