Abstract
A simple method to overcome the problem of large beam divergence and compensate for the astigmatic difference in the output beam of an asymmetric unstable ring resonator is proposed. The method is based on suitably shaping the outer surface of the output mirror. The results indicate that it is possible to select the curvatures of the output surface so that a collimated output beam is obtained in the two orthogonal planes over a fairly wide range of spacings between the focusing elements.
