PROBLEM TO BE SOLVED: To provide a combined laser source capable of generating high luminance at low cost. SOLUTION: The combined laser source includes a plurality of semiconductor lasers LD1-LD4 which contain light-emission elements separately and hermetically sealed; collimator lenses C1-C4 which collimate each of the plurality of laser beams emitted from the plurality of semiconductor lasers LD1-LD4; an optical condensing system, which is comprises a condensing lens 20 for receiving, condensing and optically combining the plurality of laser beams. Among deflection members P1-P3, among the plurality of laser beams, the laser beams, emitted in the direction different from the optical axis of the optical condensing system, are deflected in the optical axis direction and made incident to the optical condensing system, wherein the laser beams condensed by the optical condensing system are made incident on a fiber 30 and are multiplexed.
