Abstract:
1. A method for increasing the brightness of a semiconductor laser diode array, the method comprising the steps of: (a) providing a fiber coupled diode array coupled to a diode fiber bundle having a core fiber and a plurality of optical fibers concentrically disposed relative to said core fiber, said diode array coupled to said optically coupled to said concentrically disposed fibers; (b) providing a dual clad fiber formed with a core, an inner cladding and an outer cladding, said dual clad fiber configured with an inner cladding having sufficient area to optically mate with said concentrically disposed optical fibers; (c) providing a Stokes seed source; (d) optically coupling said plurality of optical fibers to said inner cladding; and (e) optically coupling said Stokes seed source to said core.
