    摘要： A laser oscillator comprising a laser resonator having a plurality of mirrors for directing the laser energy from source to exit apertures, the mirrors being constructed and mounted adjustably for reducing parasitic oscillations. The mirrors are mounted in adjusting members that have channels therein for coolant and are provided with heat insulating members that minimize heat gradients and unwanted heat transfers that may result in the distortion of the reflecting surfaces. In addition, the mirrors are angled so that light paths are defined that present a Z-shaped turning pattern. Apertures proximate to the mirrors through which the light beams are directed are offset from a common plane so that a reflective surface is not within the aperture of the opposing reflective surface. One or more of the apertures can be so offset to reduce the possibility of parasitic oscillations. Further, the reflectors can be angled and the apertures sized so as to eliminate parasitic oscillations.

    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 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.
