ABSTRACT:
A solid-state laser comprises a columnar laser rod having a central longitudinal axis, a total reflection mirror arranged coaxially of the laser rod in facing relation to one end face thereof, and a half mirror arranged coaxially of the laser rod in facing relation to the other end face thereof. The pumping light is emitted from a plurality of laser diodes arranged in an array laterally spaced from the laser rod in parallel thereto. A cylindrical lens arranged between the laser rod and the array of laser diodes serves to focus the emitted pumping light on the central longitudinal axis of the laser rod. The active substance in the laser rod is excited by the thus focused pumping light to generate a laser beam axially of the laser rod.
