HIGHLIGHTS
- who: ANGIE L.S. NAVARRO and collaborators from the - Universidad Industrial de Santander, Bucaramanga, Colombia have published the research: Fraunhofer diffraction pattern of a Gaussian beam passing through a photorefractive crystal BGO, in the Journal: (JOURNAL)
- what: The authors show that for the BGO photorefractive crystal in addition to the wavefront curvature and the change in the refractive index of the medium due to the light intensity there is a third contribution affecting the medium-induced nonlinear phase shift; the latter is related to the additional change in the refractive index produced by the photorefractive . . .
