Abstract
A method and apparatus for generating bright light sources includes a first plurality of semiconductor lasers in which each of the first plurality of semiconductor lasers emits a beam of light of a first frequency; a second plurality of semiconductor lasers in which each of the second plurality of semiconductor lasers emits a beam of light of a second frequency; a first bundle of optical fibers for receiving the light from ones of the first plurality of semiconductor lasers and providing a first combined laser beam of a predetermined shape and having a cross-sectional area and a solid angle; a second bundle of optical fibers for receiving the light from ones of the second plurality of semiconductor lasers and providing a second combined laser beam of a predetermined shape and having a cross-sectional area and a solid angle; and frequency responsive optics for combining the first and second combined laser beams into a composite laser beam, the composite laser beam having substantially the same product of cross-sectional area and solid angle as each of the first and second combined beams.
