Abstract
A laser light source is equipped with a semiconductor light-emitting device, a first wavelength selector, and a second wavelength selector. The first and second wavelength selectors are used to select the wavelength of the light emitted from the light-emitting device, and constitute an external resonator. The semiconductor light-emitting device is provided with a stripe, which is formed oblique to the cleaved end facets of the light-emitting device that do not constitute the external resonator. The end facets of the semiconductor light-emitting device are provided with coatings, which become antireflective coatings with respect to the selected wavelength.
