Abstract
The laser resonator includes 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, and at least two laser cavity mirrors. The 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. 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.
