Abstract

The features of fundamental modes in large-aperture unstable resonators with helical mirrors are for the first time to our knowledge investigated via computer simulation. It is shown that a large-aperture laser can oscillate at a single transverse mode with axially symmetric intensity and nonzero topological charge determined by the charge of the helical coupling mirror. Energy efficiency of such a laser does not differ from that for conventional unstable cavity.
