Patent ID: 8670180

Claim:
A multi-output laser system comprising: a wavelength beam combiner configured to produce a multi-wavelength asymmetrical beam profile, comprising: a plurality of beam emitters each configured to generate optical radiation having a unique wavelength; an optical focusing element arranged to intercept optical radiation from each of the plurality of beam emitters and combine the optical radiation along a beam combining dimension to form a multi-wavelength asymmetrical beam profile; a diffraction element positioned at a region of overlap of the optical radiation to receive and transmit the multi-wavelength asymmetrical beam profile; 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; an optical symmetrizing element configured to symmetrize the multi-wavelength asymmetrical beam profile; and an optical apportioning element configured to apportion the symmetrized beam and direct each portion to a distinct location.
