Applied Optics, 1984
The design of a coupling between a semiconductor laser and a single-mode fiber, or between any two optical or acoustical elements that support Gaussian modes, is presented as a trade-off among coupling efficiency T(a), offset misalignment tolerance d(e), and angular misalignment tolerance theta(e).

A generalization of the Gaussian beam is obtained by introducing a complex-valued shift in the transverse dimension. The resulting beam has a Gaussian intensity distribution with width varying as an ordinary Gaussian beam, but whose peak traces an inclined linear trajectory. The wave fronts are displaced laterally in a sheared fashion. This generalized

We demonstrate the existence of the Ince-Gaussian beams that constitute the third complete family of exact and orthogonal solutions of the paraxial wave equation. Their transverse structure is described by the Ince polynomials and has an inherent elliptical symmetry.

Beam profile flattener for Gaussian beams
Optics Letters, 1993We describe a novel technique to make a Gaussian laser beam profile spatially flat. We exploit the angular dependence of the transmission of an étalon to tailor the spatial profile to the desired form. A simple analysis shows why our method works so well and how an étalon could be tuned to give the optimum results at all wavelengths. This technique has

Gaussian Beams in Turbulent Media
Applied Optics, 1970The propagation of a gaussian beam in a turbulent medium is investigated by the geometrical optics method. The correlation function as well as the structure function of the phase fluctuations at two points of an imperturbed wavefront are derived in a closed form in the two limiting cases when the points belong to two almost parallel rays or to two ...

Mountain Waves and Gaussian Beams
Multiscale Modeling & Simulation, 2007This paper is concerned with Gaussian beams, defined as approximate solutions to hyperbolic partial differential equations that are concentrated on a curve in space-time. The authors explore in this paper a method to compute the (in time) stationary wave field that results from steady air flow over the topography as a superposition of Gaussian beams ...
