摘要: A semiconductor laser includes an active layer formed on a substrate and a pair of cladding layers sandwiching the active layer. On at least one of resonator end faces of the semiconductor laser, a first dielectric film with hydrogen added therein is provided. Between the first dielectric film and the resonator end face, a second dielectric film for suppressing the diffusion of hydrogen is provided. Even when a semiconductor laser with an end face coating film including a hydrogen-added film is exposed to high temperatures, peeling of the end face coating film and deterioration of the end face coating film can be suppressed.

摘要: A laminated core for dynamoelectric machines and so on is formed of thin sheet core pieces each blanked into a predetermined configuration and stacked one upon another and are successively welded at a plurality of weld zones of an edge of each core piece by continuous or spot irradiation of laser beams so that the core pieces are combined together. The core piece constituting one of two end faces of the core has first notches formed in one half of the weld zones of the core piece. The core piece constituting the other end face of the core has second notches formed in one half of the weld zones of the core piece constituting the other end face of the core. The first notches are shifted from the second notches by 90 degrees.
