Patent ID: 7427522

Claim:
A method of producing a short-wavelength laser module, the method comprising: a first securing step of securing an optical wavelength conversion device on a sub-mount using an adhesive that is cured by irradiation with ultraviolet light, a second securing step of securing said sub-mount, on which said optical wavelength conversion device is secured, inside a package using an adhesive that is cured by heating, an ultraviolet irradiation step of irradiating ultraviolet light to accelerate the polymerization of said adhesive that is cured by the irradiation with said ultraviolet light, a heating step of carrying out an additional heating concurrently with or after said ultraviolet irradiation step to accelerate the polymerization of said adhesive that is cured by said heating, and a sealing step of sealing said package to hermetically seal the inside of said package; wherein the sealing step is carried out after the ultraviolet irradiation step and after the heating step; and wherein said package is sealed with a bonding adhesive and said bonding adhesive does not make contact with the atmosphere inside said package.
