摘要： 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.

摘要： A variety of dense wavelength beam combining (DWBC) apparatuses are described herein that combine a plurality of individual input beams into a single output beam. DWBC apparatuses contemplated herein are open-loop configurations, i.e. configurations where the wavelength selective optics of a feedback generation system are decoupled from abeam combining system that combines a plurality of input beams each having a wavelength selected from a range of different wavelengths. Specifically, each constituent beam of the combined output beam produced by the beam combining system traverses an optical path that does not include the wavelength-selective optics of the feedback generation system. DWBC apparatuses contemplated herein further provide for matching the wavelength-dependent angular dispersion functions of optics of the feedback generation system with the wavelength-dependent angular dispersion functions of optics of the beam combining system.
