1. An endoscope illumination system, comprising: a first LED light source which emits light of a first color; a rod positioned to receive the light of the first color, wherein the rod comprises a luminescent material which absorbs the light of the first color and, in response, emits by fluorescence, fluorescent light of a fluorescent color different than the first color; a second LED light source which emits second light of a second color different than the fluorescent color; a third LED light which emits third light of a third color different than the fluorescent color and different than the second color; a fourth LED light which emits fourth light of a fourth color different than the fluorescent color and different than the second color; a laser light source which emits coherent light; a plurality of dichroic elements which combine the fluorescent light, the second light, the third light, the fourth light, and the coherent light into a single coaxial beam of output light; and an output adapter operative to receive a light guide and couple the beam of output light into said light guide.
