FIBER LASER LIGHT SOURCE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a fiber laser light source device capable of reducing speckle noise when being used as a light source of a projector apparatus.SOLUTION: A fiber laser light source device includes: a light source part having a plurality of fiber lasers each of which includes a resonator that comprises a pair of mirrors and is disposed at both end faces of an optical fiber; and an optical system configured to synthesize a laser beam emitted from each fiber laser in the light source part. The light source part has two kinds or more of fiber lasers in which at least one of incline angles at both end faces of the optical fiber relative to an axis of the optical fiber is different from each other.
