ABSTRACT:
A single axis resonator for use within a laser having an annular gain region. The single axis resonator extracts optical power from the annular gain region by the use of a beam expander, reflaxicon, corner cube and output coupler, wherein the optical axis of the resonator passes through the center of the output coupler. The reflaxicon transforms a substantially elliptically-shaped beam into a crescent-shaped beam which closely resembles the shape of a section of the annular gain region. The crescent-shaped beam is reflected through the gain region several times to build up energy before being translated back into its original shape for reflection out of the laser by the output coupler.
