Abstract:
1. A method for producing a nitride semiconductor laser light source, the nitride semiconductor laser light source comprising a nitride semiconductor laser chip, a stem for mounting the laser chip thereon, and a cap for covering the laser chip, the laser chip being encapsulated in a sealed container composed of the stem and the cap, the method comprising the steps of: an ashing step of cleaning a surface of the laser chip, the stem, and the cap, the ashing step comprising exposing the surface of the laser chip, the stem, and the cap with ozone or an excited oxygen atom; and a capping step comprising: after the ashing step, supplying a first gas onto the surface of the laser chip, the stem, and the cap; and encapsulating, in an atmosphere of the first gas, the laser chip in a sealed container composed of the stem and the cap.
