Abstract
A laser source assembly (210) for generating an assembly output beam (212) includes a first laser source (218A), a second laser source (218B), and a dispersive beam combiner (222). The first laser source (218A) emits a first beam (220A) having a first center wavelength, and the second laser source (218B) emits a second beam (220B) having a second center wavelength that is different than the first center wavelength. The dispersive beam combiner (222) includes a common area 224 that combines the first beam (220A) and the second beam (220B) to provide the assembly output beam (212). The first beam (220A) impinges on the common area (224) at a first beam angle (226A), and the second beam (220B) impinges on the common area (224) at a second beam angle (226B) that is different than the first beam angle (226A). Further, the beams (220A) (220B) that exit from the dispersive beam combiner (222) are substantially coaxial, are fully overlapping, and are co-propagating.
