    摘要： A GaAs semiconductor laser includes a GaAs semiconductor laser element, and a Cu heat sink attached to the GaAs semiconductor laser element through the use of an In solder. The GaAs semiconductor laser element includes an active layer sandwiched by cladding layers, and a substrate upon which various layers are formed. The GaAs semiconductor laser element is constructed so that the active layer is separated from the mounted surface by at least a distance which corresponds to 35 % of the entire thickness of the GaAs semiconductor laser element, thereby minimizing the stress applied to the active layer.
