A semiconductor light source includes a laser and at least one phosphor, wherein the laser includes a semiconductor body having at least one active zone that generates laser radiation, at least one resonator having resonator mirrors and having a longitudinal axis is formed in the laser so that the laser radiation is guided and amplified along the longitudinal axis during operation and the active zone is located at least partially in the resonator, and the phosphor is optically coupled to the resonator in a gap-free manner so that in the direction transverse to the longitudinal axis at least part of the laser radiation is introduced into the phosphor and converted into a secondary radiation having a greater wavelength.
