Abstract: In accordance with various embodiments, a multi-wavelength beam output is formed by stabilizing beams each to a unique wavelength with a stabilizing dispersive element, which reflects a portion of the beam back to its emitter to stabilize the beam and transmits the stabilized beam. The stabilized beams are then transmitted to a combining dispersive element that combines the stabilized beams into the multi-wavelength beam output.
