Solid-state laser unstable resonators with tapered reflectivity mirrors: the super-Gaussian approach
TLDR
In this article, a general procedure for treating solid-state laser unstable resonators with tapered reflectivity mirrors within the framework of geometrical optics is presented, where a suitable choice of the analytical form of the reflectivity profile makes possible the derivation of simple design equations for the resonator parameters.Abstract:
A general procedure for treating solid-state laser unstable resonators with tapered reflectivity mirrors within the framework of geometrical optics is presented. A suitable choice of the analytical form of the reflectivity profile, which can simulate many experimental devices, makes possible the derivation of simple design equations for the resonator parameters. Experiments performed with a pulsed Nd:YAG laser containing a variable-reflectivity output coupler, implemented with vacuum evaporation techniques, are discussed. >read more

Flattened gaussian beams
TL;DR: In this paper, a simple propagation law is found for light beams of various orders and their field distribution across the waist plane is similar to that produced by an ordinary gaussian beam except that the central region is flattened.

Generalized Bessel-Gauss beams
TL;DR: In this article, a superposition model for Bessel-Gauss beams is described, in which higher orders are included, leading to a different class of beams, namely the modified Bessel Gauss beams.

Light Beams with Flat-Topped Profiles
TL;DR: This proposal leads to the introduction of a set of light beams with flat-topped profiles that can be expressed as a finite series of lowest-order Gaussian modes (TEM(00)) with different parameters.

Propagation of various flat-topped beams in a turbulent atmosphere
TL;DR: In this article, the average intensity of flat-topped beams propagating in a turbulent atmosphere is derived in a tensor form, and the formulae derived can be easily reduced to those for flat-top beams in free space.

Large-size Gaussian mode in unstable resonators using Gaussian mirrors
Nathalie McCarthy,P. Lavigne +1 more
TL;DR: Gaussian modes with large sections have been experimentally produced in Cassegrain resonators using Gaussian reflectivity convex couplers and the far field of the beam, which was coupled through a Gaussian coupler, was found to be free from secondary rings.
