    摘要： In a laser-light source: submounts each being made of a material having a thermal expansion coefficient of 3.5 to 6.0×10−6/° C. and having a thickness of 200 to 400 micrometers are separately formed on a heat-dissipation block made of copper or copper alloy; a single-cavity nitride-based semiconductor laser chips are respectively mounted junction-side-down on the corresponding submounts; an optical condenser system collects laser beams emitted from the semiconductor laser chips, and couples the collected laser beams to a multimode optical fiber. A bonding surface of each semiconductor laser chip is bonded to a bonding surface of a corresponding submount through a metalization layer and an Au—Sn eutectic solder layer each of which is divided into areas.

    摘要： In a laser light multiplexing apparatus: a collimating optical system collimates light beams emitted from semiconductor lasers so that the slow axes of the light beams become coplanar, and optical axes of the light beams become parallel to each other; a light beam rearrangement optical system constituted by prisms respectively arranged in correspondence with the light beams rearranges the light beams in such a manner that directions of the fast axes of the light beams are changed at different locations along a direction in which the light beams propagate, and the fast axes of the light beams become coplanar; and a convergence optical system converges a bundle of the light beams rearranged by the light beam rearrangement optical system, in directions of the fast axes and the slow axes of the light beams, and makes the converged bundle of the light beams enter an optical fiber.
