Thin film coatings having a radially variable reflectance with a circular symmetry are used for obtaining diffraction limited laser beams from unstable resonators. Different approaches are used for the design of such coatings with a consequent different final coating structure that contains one or more profiled thickness layers. Some design methods are discussed with reference to reflected intensity and phase profiles and the fabrication techniques for coatings at different wavelengths are illustrated.
