A high power light source includes one or more diodes (52) that may produce relatively coherent light of a desired intensity. The diodes (52) may be pulsed to provide light as desired. The light projected by the diodes (52) passes through a combiner (54), which combines the light from the different diodes (52) and passes the combined light to an incoherence apparatus (56). The incoherence apparatus (56) may include a rotating surface relief phase device such as an optical hologram, a computer generated hologram, or a diffractive optical element with random phase modulation. The incoherence apparatus (56) may include a rotating fiber conduit comprising a plurality of multi-mode fiber cores. The incoherence apparatus (56) renders the combined light incoherent and passes it to an illuminator apparatus (58) that focuses the incoherent combined light onto an image plane.
