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.

Abstract: A method for generating output laser pulses includes generating input laser pulses having an equal pulse duration, and coupling the input laser pulses into an optical actuator. A dispersion of the optical actuator is settable. The method further includes setting the dispersion of the optical actuator for a current input laser pulse, so that a pulse duration change caused by a change of a temperature of at least one component and/or by a change of an ambient temperature is compensated for, and that an associated output laser pulse has a pulse duration corresponding or nearly corresponding to a target pulse duration.

Abstract: An external cavity laser apparatus includes a plurality of laser modules collectively including a plurality of beam emitters that collectively emit a plurality of emitted beams. Each laser module includes a base comprising a plurality of stepped platforms, one of the plurality of beam emitters being secured on each platform of the plurality of stepped platforms, and a plurality of module reflectors, one of the plurality of module reflectors being secured on each of the plurality of stepped platforms to receive radiation from a respective one of the plurality of beam emitters located on a same stepped platform. The external cavity laser apparatus further includes an angular dispersive optic and a polarized beam splitter.
