    • A semiconductor laser device is provided to repress saturation of a light emitting efficiency in a high output operating state to be saturated. A semiconductor laser device includes a first light emitting unit and a second emitting unit having a same resonator length formed on a substrate. The first light emitting unit and the second emitting unit have a first clad layer of a first conductive type, an active layer(13,23) formed on the first clad layer, and a second clad layer of a second conductive type. The first light emitting unit and the second emitting unit are a stripe structure. The stripe structure of the first emitting unit have a width varied along to a resonator direction. The stripe structure of the second emitting unit have a width varied along to the resonator direction. A length of a wavelength of the first light emitting unit is longer than that of the wavelength of the second light emitting unit.
