1. A scalable wavelength beam combiner system comprising:
- a plurality of modular laser input devices, wherein each modular laser input device includes;
at least one beam emitter configured to produce an electromagnetic beam, andat least one transform optic, wherein each transform optic causes the emitted beams to overlap at a dispersive element, and wherein the dispersive element transmits the overlapped beams as a single output 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.
