    摘要: A silent discharge type pulse laser device having a pair of opposing electrodes, at least one of which is an electrode covered by a dielectric, which is mounted opposite to a metallic electrode with a silent discharge space in between, a laser resonator consisting of a total reflection mirror and a partial reflection mirror mounted opposite to each other with the silent discharge section in between, a source of high frequency voltage for supplying to the pair of electrodes a high frequency voltage having a predetermined period for silent discharge, and a controller for controlling the high frequency voltage from the source with respect to a first interval and a second interval that form a period longer than the period for silent discharge. The high frequency voltage is supplied to the silent discharge section at a first peak voltage value during the first interval and at a second peak voltage value during the second interval, wherein the second peak voltage value is sufficient to cause a discharge but insufficient to excite laser oscillation.

    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.
