ABSTRACT:
To achieve a high power, large area, substantially monochromatic solid-state light source, the outputs of hundreds of discrete injection lasers are combined. For the combination, each laser is butt coupled to one end of its separate large core multimode fiber. Groups of fibers are packaged in linear arrays in separate ribbon cables and the ribbon cables are stacked in a two-dimensional rectangular array. The free ends of the fibers terminate in a common plane to make available, at such plane, a high power, large area, source of light. In one embodiment, separate fibers are coupled to the two ends of each injection laser to utilize the light emitting at both facets of the laser.
