摘要： In various embodiments, wavelength beam combining systems feature multiple beam emitters each emitting an individual beam, as well as multiple micro-optics arrangements each disposed optically downstream from a beam emitter to intercept the beam emitted thereby and direct the beam toward a dispersive element for combination into a multi-wavelength output beam.
