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. The spectral beam combining system may further comprise at least one additional diffractive optical element or diffraction grating for dispersion compensation that reduces the effects of angular dispersion of wavelength components within the input channel. This spectral beam combining system facilitates combining an increased number of wider spectral channels thereby potentially allowing higher optical power, e.g., within each fewer channel lasers. The combined beam focal spot shape profile is maintained as spectrum width or central spectrum wavelength of any one or all input channels is changed.
