Abstract

Various embodiments of a multi-wavelength beam combiner are disclosed. Some embodiments comprise a plurality of lasers adapted to produce light and lenses arranged to receive and focus the light produced by each of the plurality of lasers. A wavelength dispersive element is arranged to receive the light produced by a combination of each of the plurality of lasers and the plurality of lenses, such that the light produced by each combination forms a region of overlap at the wavelength dispersive element. The wavelength dispersive element is configured to provide a multi-wavelength beam of light comprising the light produced by each combination of the plurality of lasers and the plurality of lenses. At least one partially reflective device is configured to receive at least a portion of the multi-wavelength light and to reflect a portion of the multi-wavelength light.
