Abstract
A pumped fluorescent light source includes one or more mirrors that direct pumping light from one or more pump sources on a fluorescent body having a planar top surface and a convex back surface. The top surface may be coated with an anti-reflective coating and the back convex surface may be coated with a reflective coating to improve efficiency. The body top surface may also be roughened to scatter a portion of the excitation light provided from the mirror(s) to generate a white output beam. The mirror(s) have reflective surfaces disposed outside of a collection area of an output beam of the light sources, so that the collection area is not obstructed by the mirror(s). The light source also includes a collecting lens for collecting the light emitted by the body. The mirror may be a single parabolic mirror that focuses the excitation light on the body to stimulate emission.
