Abstract

A simple and versatile laser output coupler with a radially variable reflectivity profile is described. This device, based on a radially variable Fabry–Perot interferometer made of two suitable spherical mirrors, provides a variety of reflectivity profiles that are particularly useful for generating large-cross-section diffraction-limited beams with unstable resonators.
