Abstract
In various embodiments, wavelength beam combining systems feature multiple beam emitters each emitting an individual beam, as well as multiple micro-optics arrangements each disposed optically downstream from a beam emitter to intercept the beam emitted thereby and direct the beam toward a dispersive element for combination into a multi-wavelength output beam.
Claims21
A method of producing a multi-wavelength output beam, the method comprising:
- emitting a plurality of individual beams from one or more emission points;
- rotating each individual beam at a different angle to thereby direct the beams toward each other;
- thereafter, focusing the rotated beams to overlap the beams at a common focal point;
- wavelength-dispersing the focused beams;
- propagating a first portion of the dispersed beams back to the one or more emission points;
- and
- propagating a second portion of the dispersed beams as the multi-wavelength output beam.
