An objective is to provide a light source device having a light emission source such as a semiconductor laser (LD), an LED and a lamp, and an optical part such as a lens and a fiber for transmitting, transferring and light-focusing, in which, by controlling the amount of sulfate ions inside the device at a low level, adhesion of ammonium sulfate to the optical part can be prevented. The light source device includes a light source for emitting light, an optical part for processing light emitted from the light source, and a housing in which the optical part is housed, or to which the optical part is mounted, and the housing is formed by machining material that includes no sulfur component, and the material is exposed on the surface thereof.

The invention provides an end-face-processing jig that allows the formation of a reflectance control film on an end face of a semiconductor laser body while preventing possible degradation due to catastrophic optical damage (COD) of a semiconductor laser, and a method of manufacturing a semiconductor laser employing such an end-face-processing jig. A window part of the end-face-processing jig is made of at least one of an oxide and a nitride, and semiconductor laser bars are fixed by the end-face-processing jig so that their end faces are exposed through a window of the window part. In this condition, a reflectance control film is formed on the end faces of the semiconductor laser bars for the manufacture of a semiconductor laser. This prevents a metal from being taken in the reflectance control film, thus preventing the absorption of light caused by a metal taken in the reflectance control film. It is thus possible to form a reflectance control film on the end faces of semiconductor laser bars while preventing possible degradation due to COD of a semiconductor laser.

A GaN laser, includes a coating film on a front end surface through which laser light is emitted. The coating film includes a first insulating film in contact with the front end surface and a second insulating film on the first insulating film. The optical film thickness of the second insulating film is an odd multiple of λ/4 with respect to the wavelength λ of laser light produced by the semiconductor laser. The adhesion of the first insulating film to GaN is stronger than the adhesion of the second insulating film to GaN. The refractive index of the second insulating film is 2 to 2.3 thick. The first insulating film is 10 nm or less. The first insulating film is an oxide film having a stoichiometric composition.

A semiconductor laser device includes a semiconductor laser body including a resonator and having a front end face and a rear end face facing each other, the resonator being located between the front end face and the rear end face. The front end face emits principal laser light. A reflectance control film is disposed on the front end face or the rear end face of the semiconductor laser body and is made up of either an aluminum oxide film or a five-layer film including the aluminum oxide film disposed such that it is the layer in the five-layer film farthest from the front end face or the rear end face. A silicon oxide film is disposed on the aluminum oxide film of the reflectance control film and has a thickness of 20 nm or less.

A semiconductor laser device comprises a GaN substrate having a refractive index of 3.5 or below, a semiconductor layer laminated on the substrate, and a pair of facets forming a resonator and in face-to-face-relation to each other in a direction perpendicular to the direction of the laminated layer. One of the facets of the resonator includes a low reflection film, of a first dielectric film, a second dielectric film, a third dielectric film, and a fourth dielectric film. When the refractive indexes of these films are taken as n1, n2, n3, and n4, n1=n3 and n2=n4. The following relationship between the first dielectric film and the third dielectric film, and between the second dielectric film and the fourth dielectric film is established, nd+n′d′=pλ/4, where p is an integer, and λ is oscillation wavelength of a laser beam generated by the semiconductor laser device.
