    摘要: A laser device having an infrared laser medium and an aperture member disposed within a resonator in which the mode symmetry is improved. An optical resonator including a total reflecting mirror and a partial reflecting mirror disposed at opposite ends of a gap between electrodes is arranged parallel to an optical axis and orthogonal to a gas flow direction. An aperture member disposed along the optical axis between the mirrors on the side of the partial reflecting mirror has the form of a ring having an axis coinciding with the optical axis. Plural laser beam detecting elements are disposed on the inner peripheral area of the ring. The angular positions of the mirrors are controlled such that a difference in outputs of the detecting elements is minimized.

    摘要: In a laser device employing an optical resonator which is constructed of a total reflection mirror and a partial reflection mirror, a total reflection plane having an opening is interposed between the partial reflection mirror and the total reflection mirror, the total reflection plane may be formed of, for example, a dielectric thin film or a metallic totally-reflective thin film produced with a cluster ion beam, and the total reflection plane and the total reflection mirror are arranged so as to establish a resonant state. The total reflection plane is formed on an aperture of the partial reflection mirror. The opening of the total reflection plane may be ring-shaped, or a plurality of openings may be provided. The total reflection plane may be located centrally. In a laser device employing an unstable optical resonator, a beam deriving mirror may be disposed within the optical resonator.

    摘要: A solid state laser apparatus is provided to generate a high quality and high power laser beam, and a laser machining apparatus is provided to perform laser machining by a laser beam generated from the solid state laser apparatus. In the solid state laser apparatus, a laser resonator includes a solid state component cooled in a cylindrical pipe by contacting liquid which is introduced through an inflow opening and discharged through an outflow opening, the solid state component having larger refractive index than that of the liquid, a light source turned ON by a power source to excite the solid state component, and an optical system transmitting light from the light source to the solid state component. Further, a surface roughness of the solid state component is adjusted so as to adjust an excitation distribution in a section of the solid state component. The solid state component further includes moving means for moving a reflection mirror and a condensing lens in a direction of an optical axis of the laser resonator, and a housing accommodating an image transferring optical system. A laser beam is generated from the laser resonator, and is externally derived and used to perform the laser machining.
