We consider the three-layered symmetric structure consisting of inner layer with Kerr type defocusing nonlinearity sandwiched by photorefractive crystals with diffusion nonlinearity …
A model of an interface between a uniaxial crystal with the diffusion mechanism of formation of a nonlinear photorefractive effect and crystals with both focusing and defocusing Kerr …

Nonlinear surface waves of the TM polarization propagating along the interface between crystals with Kerr and photorefractive diffusion nonlinearities are considered. It is shown that …
The energy exchange during two-wave mixing can be increased in photorefractive sillenite crystals considering thick samples (ie, large interaction lengths). Nevertheless, in thick …

In this paper, we explore the photorefractive crystal with diffusion nonlinearity mechanism covered by self-focusing Kerr-type crystal contacting with dielectric medium. Four types of …
I personlige dagbogsblade fra 1998 og 1999 med udgangspunktet i samlivet med datteren Laura på 3 år reflekterer forfatteren over sin samtid, dens mennesker og begivenheder-fra …
