Spatial coherence of optical fields in longitudinally inhomogeneous media with quadratic refractive index profiles

Abstract

We deposited SmBCO thin films on BaZrO 3 (BZO)-buffered MgO (100) substrates by an off-axis magnetron sputtering method. SmBCO films were deposited at a fixed condition on stoichiometric and Zr-rich BZO-buffered MgO substrates. We found that the crystal orientation of SmBCO films changed from a-axis to c-axis orientation by using Zr-rich BZO. We speculate that the reaction between excess Zr oxides on the buffered substrates and deposited species at the initial stage of the SmBCO deposition is important in inducing these phenomena.

Fundamental laser modes in paraxial optics: from computer algebra and simulations to experimental observation

“…In the context of paraxial optics, when the time variable t represents the coordinate in the direction of the system optical axis, say s, for wave propagation, the expressions (2.2)-(2.3) can be thought of as a generalization of Fresnel integrals [8], [9], [27], [45], [55], [83], [84], [85], [86], [100], [144]. The corresponding Schrödinger equation (2.1), with t → s, can be referred to as a generalized paraxial or parabolic wave equation [97], [100].…”

Contribution of Samara Scientists Into Computer Optics Journal Development

“…The efficiency of the application of the coherent states representation and density matrix in the tasks of propagation of partially-coherent radiation in inhomogeneous media was shown by I.N. Sisakian and his followers [80][81][82]. The behaviour of spatial coherence of optical fields in the media with general-squareindex and arbitrary regular longitudinal inhomogeneity was investigated.…”
