ABSTRACT:
The invention relates to a new configuration for a laser resonator for use in combination with a solid-state laser gain medium contained within the core of a planar waveguide. The resonator has a substantially confocal negative branch unstable resonator configuration in a lateral direction, a low loss waveguide resonator configuration in a transverse direction, and the focal point of the unstable resonator is disposed outside the planar waveguide to avoid optical damage or breakdown in the gain medium. The preferred embodiment includes an effective means of transverse mode selection for the case when the planar waveguide is of the multi-mode type. The invention also provides a new low loss waveguide resonator configuration which may be used with planar waveguide gas lasers.
