Claim Text:
1. A laser resonator comprising: a first resonator wall; a second resonator wall that is substantially parallel to the first resonator wall and is separated from the first resonator wall in a first transverse direction thereby defining a gap having a gap width between the first and second resonator walls; a plurality of laser cavity mirrors comprising: wherein the plurality of laser cavity mirrors are arranged to allow an intra-cavity laser beam to reflect from the output coupling mirror thereby forming a first beam spot on the output coupling mirror; wherein the plurality of laser cavity mirrors are arranged to allow the intra-cavity laser beam to reflect from the first curved mirror thereby forming a second beam spot on the first curved mirror, and wherein the first curved mirror has a radius of curvature such that the reflection of the intra-cavity laser beam from the first curved mirror causes the first beam spot on the output coupling mirror to have a substantially symmetric shape.
