The phase shift induced on a Gaussian beam interacting with a nonlinear medium determines the far field diffraction pattern characteristics. It is usual to consider that the induced phase shift by a nonlinear media is due only to the effects of the r

In this theoretical-experimental study, we use the Fresnel-Kirchhoff diffraction theory to simulate the formation of the far-field diffraction pattern of a divergent Gaussian beam propagated through a BGO photorefractive crystal. We show that for the

The interplay between gain and scattering of light propagating in disordered media allows operation of random lasers (RLs)-lasers without conventional optical cavities. In the present paper, we review our recent contributions in this area, which incl

Morphological, structural and optical properties of Nd3+/Yb3+ codoped Al4B2O9 nanopowders prepared by the polymeric precursor method were investigated. The compounds previously heat-treated at 900 °C were characterized by X-ray diffraction (XRD) and
