Optics letters, 1988•opg.optica.orgA new class of tapered reflectivity mirrors with a super-Gaussian profile R∞ exp (-kr^ n) is
introduced, and a geometrical-optics approach for analysis and design of unstable
resonators made with these mirrors is presented. 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.
