Abstract: A semiconductor laser module includes a semiconductor laser that outputs laser light; an optical fiber that guides the laser light; a lens that couples the laser light, which is output from the semiconductor laser, with the optical fiber; a base that is substantially tabular in shape and that has the semiconductor laser, the optical fiber, and the lens fixed thereon either directly or indirectly; and a housing which houses the base and fixes the base either directly or indirectly. Among faces of the base, a face on a side that is fixed either directly or indirectly to the housing includes a junction plane that is joined to the housing either directly or indirectly, and a detachment plane that is detached to remain unfixed from the housing.

Abstract: A semiconductor laser module 1 is mainly composed of a package 3, a semiconductor laser 5, lenses 7, 9, 13, reflecting mirrors 11, an optical fiber 15, and the like. The package 3 is composed of a bottom part and side surfaces 19a, 19b. The side surfaces 19a, 19b stand erect approximately vertical to the bottom part of the package. In the semiconductor laser module 1, a plurality of semiconductor laser installation surfaces 17 are formed in a step-like shape. On each semiconductor laser installation surface 17, a semiconductor laser 5 is installed. A lens 7 is arranged at the anterior (in the emission direction) of the semiconductor laser 5. Moreover, a lens 9 is arranged further to the anterior. A reflecting mirror 11 is fixed to the side surface 19a, which is provided facing the emission direction of the semiconductor laser 5.

Abstract: A laser apparatus includes light source elements outputting laser beams; a wavelength-selecting element disposed in an optical path of each of the laser beams and configured to cause light in a predetermined wavelength band to selectively transmit therethrough; and a partially transmissive-reflector that receives the light transmitted through the wavelength-selecting element, reflects a part of the input light toward the wavelength-selecting element, and causes its remainder to transmit therethrough. The wavelength-selecting element causes a part of the respective laser beams output from the respective light source elements to selectively transmit therethrough, the partially transmissive-reflector reflects a part of the respective transmitted laser beams, and the wavelength-selecting element causes a part of the respective reflected laser beams to transmit to return to the light source elements, and each of the light source elements preferentially oscillates at a wavelength of the laser beam that transmits through the wavelength-selecting element.
