Abstract
An external cavity laser type light source including a light emitting element, a wavelength selection element for selecting a wavelength of light emitted from the light emitting element and for returning light to the light emitting element, and an optical branch element arranged between the light emitting element and the wavelength selection element. In the external cavity laser type light source, selected light sent from the wavelength selection element is branched by the optical branch element, and one branched component is taken out as output light.
