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.

Abstract: A resonator for a laser includes a first resonator wall and a second resonator wall with a lasing medium disposed in a gap therebetween. The resonator further includes a first mirror disposed at a first end of the first and second resonator walls and a second mirror disposed at a second end of the first and second resonator walls. The mirrors cooperate to form an intra-cavity laser beam that travels along a plurality of paths through the lasing medium. Furthermore, the first mirror and the second mirror form a laser resonator for a parasitic laser mode. A parasitic mode suppressor is located within the superfluous region.

Abstract: The resonator includes a lasing medium having a thickness, a first mirror disposed at a first end of the lasing medium and a second mirror disposed at a second end of the lasing medium. The first and second mirror cooperate to fold an intra-cavity laser beam along a plurality of paths through the lasing medium, thereby defining a boundary of a superfluous region within the resonator, wherein the intra-cavity laser beam does not pass through the superfluous region. The first mirror and the second mirror form a laser resonator for a parasitic laser mode, a portion of which is located within the superfluous region. A parasitic mode suppressor is located within the superfluous region of the resonator.

Abstract: A waveguide aperture beam conditioner includes an input port section having an input port that receives an aberrated laser beam, an elongated waveguide body formed from an opaque material and having internal bore formed therethrough, and an output port that receives the waveguided beam and outputs a conditioned output laser beam. An inner surface of the internal bore forms a waveguide for the focused output beam and thereby generates a waveguided beam.
