Abstract
A spectral beam combining system includes a spectral channel splicer comprising a plurality of reflectors and a spectral beam combiner comprising a diffraction optical element such as a diffraction grating. This spectral beam combining system may facilitate combining an increased number of spectral channels thereby producing higher optical power of the combining beam system.
Claims20
A spectral beam combining system comprising:
- a plurality of input channels comprising a plurality of respective laser sources configured to output respective input beams along respective optical paths, different input channels comprising different wavelengths;
- a plurality of reflectors, individual reflectors positioned to receive respective channels of the plurality of channels;
- and
- a spectral beam combiner comprising a diffractive optical element, said spectral beam combiner positioned to receive light from said plurality of channels reflected off respective reflectors of said plurality of reflectors, said spectral beam combiner configured to direct said plurality of input beams toward the same direction thereby forming an output beam comprising said plurality of input beams combined together.
