Abstract
An optically pumped semiconductor ring laser having a plurality of reflective elements optically aligned with one another to form a ring-shaped resonant cavity. A semiconductor lasing medium is mounted within the ring-shaped resonant cavity by a transparent, heat conductive mount located within a vacuum/cooling chamber of the type which allows the passage of a laser beam therethrough. A pump beam initiates a lasing action within the ring-shaped resonant cavity to produce said laser beam and said laser beam exits the resonant cavity as a pair of outputs. An alternate embodiment of the above described semiconductor ring laser provides a semblance of unidirectional lasing operation.
