Influence of the non-uniformity of the grating along sample thickness and of grating period variation, on the diffraction efficiency optimization in a sillenite crystal …
We solved numerically the set of partial, non-linear, material rate differential equations for
different values of grating period in a photorefractive, sillenite crystal (Bi12SiO20). These …
