Abstract
An external cavity laser apparatus according to an embodiment of the invention is provided. The external cavity laser apparatus includes a plurality of beam emitters that collectively emit a plurality of emitted beams that each includes a primary component emitted beam. A first reflective element is configured to reflect the plurality of primary component emitted beams and a first polarizing optic disposed in the optical path of the plurality of primary component emitted beams is configured to rotate a polarization of each primary component emitted beam to produce a first rotated primary component beam having a first linear polarization and a second rotated primary component beam having a second linear polarization. A polarized beam splitter is configured to direct first feedback system output component beams into an output beam, and to direct second feedback system output component beams to the plurality of beam emitters as feedback beams.
