An optical illumination system for directing the radiant energy produced by an array of high-power laser fibers to a spatial modulator from which selected rays are directed to a media requiring radiation of high radiant intensity includes various lenses and an optical mixer to transfer the high energy beams of the laser emitters to the modulator. More particularly, the illumination system comprises: (a) a plurality of laser radiation sources; (b) means for transmitting rays such as a plurality of optical fibers from the laser sources to means for collimating the rays such as a collimating lens; (c) means for imaging the collimated rays such as a plurality of imaging lenses; (d) means for collimating the imaged rays such as a collimating lens; (e) means for modulating the imaged and collimated rays such as a total internal reflection modulator, wherein focalizing means such as a focalizing lens focalize the imaged and collimated rays on the modulating means; (f) lens means which receive rays from the modulating means; (g) means for separating the diffraction orders of the rays received from the lens means such as a plate having a slit; and (h) imaging means such as a telecentric objective lens for receiving rays from the separating means and forming a reduced image of the modulator.
