1. A laser system comprising:
a plurality of beam emitters each forming an external lasing cavity with an external optical element, whereby each lasing cavity stabilizes a beam emitted by the beam emitter to a different wavelength; and
disposed outside and optically downstream of each external lasing cavity, a diffraction grating positioned to receive the stabilized beams, diffract each beam, and direct first-order diffracted light from each beam toward a common direction to thereby form a multi-wavelength output beam.
