As a lightwave having a Gaussian intensity profile passes through a tilted Fabry-Perot filter,
the profile is distorted severely depending on the conditions of the parameters. This …

The formation dynamics of crossed-beam photorefractive gratings formed by the method of
two-center holographic recording in doubly doped LiNbO3 crystals is investigated in this …

By the Riemann method, a coupled wave model is derived for the ordinary-to-ordinary (OO)
