Abstract:
A method of spectral beam combining comprising the steps of projecting a plurality of laser beamlets of different wavelengths onto a first spectrally dispersive element, spatially chirping the plurality of beamlets via the first spectrally dispersive element, rearranging the spatially chirped beamlets with a beam redirecting element, and combining the beamlets into a single output beam via a second spectrally dispersive element.
