Abstract

Provided is a light source device having optical fiber arrays arranged so that different sets of RGB laser lights are focused at different depth positions, while enhancing the efficiency of light utilization. The light source device includes a plurality of optical devices each of which generate red, green, or blue laser light, a plurality of first, second, and third optical fibers through each of which the red, green, or blue laser light from a corresponding one of the plurality of optical devices is guided, and a fiber bundle combiner which forms a fiber bundle by fixedly holding together end portions of the plurality of first, second, and third optical fibers in such a manner that a plurality of optical fiber sets, each comprising three optical fibers one from the first optical fibers, one from the second optical fibers, and one from the third optical fibers, are stacked in layers.
