Gaussian beams in inhomogeneous anisotropic layered structures

Gaussian light beams in inhomogeneous media.

Vector wave solutions are obtained for the propagation of beams of light in media having slow spatial variations of the gain, loss, or index of refraction. The formalism developed here is applicable to a wide range of problems, and an exa mple considered in detail is the propagation of off-axis beams in lenslike laser materials and optical waveguides. A procedure is also described for the diagn...

Anisotropic Inhomogeneous Rectangular Thin-Walled Beams

This paper is devoted to the asymptotic analysis of the problem of linear elasticity for an anisotropic and inhomogeneous body occupying, in its reference configuration, a cylindrical domain with a rectangular cross section with sides proportional to ε and ε and clamped on one of its bases. The sequence of solutions u of the equilibrium problem is shown to converge in an appropriate topology, a...

Z-scan experiment with anisotropic Gaussian Schell-model beams.

We analyze the z-scan experiment with anisotropic Gaussian Schell-model (AGSM) beams. The expression for the cross-spectral density of the AGSM beam passing through the lens and onto the nonlinear thin sample is derived. Based on the expression, we simulate the results of the z-scan experiment theoretically and analyze the effects of the e factor (e=w(0x)/w(0y)) and the spatial degree of cohere...

Transmission and reflection of Gaussian beams by anisotropic parallel plates.

Explicit and compact expressions describing the reflection and the transmission of a Gaussian beam by anisotropic parallel plates are given. Multiple reflections inside the plate are taken into account as well as arbitrary optical axis orientation and angle of incidence.
