ABSTRACT:
A structure and method for operating a copper-vapor laser involves splitting and polarizing the exiting beam of radiation into two beams of different polarization orientations. One beam is completely reflected back to the laser medium within a first external cavity, and the other beam is partially reflected back to the laser medium in a second external cavity and is also partially transmitted to provide an output beam of short pulse duration that is selectively shaped in response to the interaction within the laser medium of the two segregated beams.
