Abstract:
1. A method for producing a nitride semiconductor laser light source, the nitride semiconductor laser light source including a nitride semiconductor laser chip, a stem for mounting the nitride semiconductor laser chip thereon, and a cap for covering the nitride semiconductor laser chip, the nitride semiconductor laser chip being encapsulated in a sealed container formed by the stem and the cap, the method comprising the steps of: a baking step of cleaning a surface of at least one of the nitride semiconductor laser chip, the stem, and the cap, the baking step including heating at least one of the nitride semiconductor laser chip, the stem, and the cap at a temperature of about 100° C. to 500° C. in a first atmosphere, the first atmosphere including a first inert gas, the first inert gas and oxygen gas, or dry air with a moisture concentration of about 1000 ppm or lower; and a capping step performed after the baking step, the capping step including encapsulating the nitride semiconductor laser chip in the sealed container formed of the stem and the cap, the capping step being carried out in a second atmosphere, the second atmosphere including a second inert gas and oxygen gas or dry air with a moisture concentration of about 1000 ppm or lower.
