Abstract
A high-power laser, especially one with a gaseous excitation medium, having an unstable optical resonator is disclosed. Fully reflecting mirrors, whose planes of curvature are parallel to one another, form the ends of the unstable optical resonator. A third mirror is concavely curved in a plane perpendicular with respect to the other two mirrors. The mirrors have a rectangular cross section and are preferably metallic. The mirrors constituting the ends of the unstable optical resonator form a confocal resonator.
