Abstract

Laser resonators employing radially variable reflectance mirrors offer a number of advantages on standard laser configurations. Different devices have been proposed to produce variable reflectance and an interesting solution consists in the use of thin film coatings with variable thickness layers. The success of thin films in this field depends on the ability to design a coating with whatever reflectance profile and to control accurately radially variable thicknesses. In this paper a design approach is proposed and two techniques for profiled layer fabrication are illustrated. Some experimental mirrors with super-gaussian profiles have been produced and tested as output couplers of a Nd:YAG laser resonator.
