Unstable laser resonators with super-Gaussian mirrors.
TLDR
A super-Gaussian mirror, built by a special evaporation technique, has been tested in an unstable resonator of a pulsed Nd:YAG laser, demonstrating its effectiveness in generating diffraction-limited beams.Abstract:
A new class of tapered reflectivity mirrors with a super-Gaussian profile R ∝ exp(−krn) is introduced, and a geometrical-optics approach for analysis and design of unstable resonators made with these mirrors is presented.

Solid-state laser unstable resonators with tapered reflectivity mirrors: the super-Gaussian approach
TL;DR: 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.

Laser beam shaping profiles and propagation.
TL;DR: In this article, the shape and width parameters of the different distributions were determined, when each profile has the same radius and slope of the irradiance at its half-height point.

Lasers with super-Gaussian mirrors
TL;DR: In this article, a theoretical and experimental investigation of unstable resonators with variable reflectivity mirrors of a super-Gaussian profile is presented, and the validity of a geometrical optics formalism for an algebraic mode calculation is discussed in comparison to the diffraction theory.

Propagation of flat-topped multi-Gaussian laser beams.
TL;DR: The multi-Gaussian beam shape is proposed as a model for aperture functions and laser beam profiles that have a nearly flat top but whose sides decrease continuously.

Diffractive analysis of unstable optical resonators with super-Gaussian mirrors.
TL;DR: It is found that for the geometrical-optics approximation to be valid, resonators with M ≤ 2 and n ≤ 8 should be designed with Neq ≥ 2, to ensure that the cavity exhibits good azimuthally symmetric transverse-mode discrimination and a super-Gaussian fundamental mode.
