Abstract

An outputcoupler with radially variable reflectivity mirror (VRM) of a supergaussian profile obtained by thin film deposition technique on a glass substrate is presented. Application to a pulsed Nd:VAG laser with a confocal pbranch unstable resonator has produced diffraction limited output beams. Output characteristics of the osci I 1 ator Wi th prof i 1 ed and nonprof i I ed (uni form) outputcoup 1 ers and the same peak reflectivity were also compared.
