Abstract
Since the invention of the laser, optical resonators using aspherical mirrors have been the subject of a few analyses, most of them purely numerical. The object was to design a stable-unstable resonator yielding a large fundamental mode with a high discrimination against higher-order transverse modes. Recently,1,2 we have presented a powerful algorithm to calculate the mirror profile necessary for a specified output beam. The approach involves an inverse-propagation method.
