Semiconductor light source

A semiconductor light source comprising a laser and at least one phosphor, wherein

• the laser comprises 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.

A semiconductor light source comprising a laser and at least one scattering means, wherein

• the laser comprises 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 scattering means is optically coupled to the resonator in a gap-free manner so that in the direction transverse to the longitudinal axis the laser radiation is introduced into the scattering means and is scattered by the same so that a coherence length of the emitted laser radiation is reduced to at most 10 μm by the scattering means.
