Abstract
A system and method for reconfiguring a plurality of electromagnetic beams to take advantage of various wavelength beam combining techniques. The reconfiguring of beams includes individual rotation and selective repositioning of one or more beams with respect to beam's original input position.
Claims17
A wavelength beam combiner comprising:
- an optical rotator configured to selectively rotate beams emitted by a plurality of beam emitters;
- a transform optic configured to receive and combine the selectively rotated beams along a beam combining dimension;
- a dispersive element positioned to receive and transmit the combined beams;
- and
- a partially-reflecting output coupler arranged to receive the combined beams from the dispersive element, to reflect a portion of the combined beams toward the dispersive element, and to transmit the combined beams as a multi-wavelength beam comprising optical radiation having a plurality of wavelengths.

A wavelength beam combiner comprising:
- a spatial repositioning element configured to spatially-reposition beams emitted by a plurality of beam emitters;
- a transform optic arranged to receive the spatially-repositioned beams and combine the beams along a beam combining dimension;
- a dispersive element positioned at a region of overlap of the combined beams to receive and transmit the combined beams;
- and
- an optical coupler configured to reflect a portion of the beams back into each of the beam emitters.
