    摘要： Matching means (2) is arranged in a power source unit (5) which is provided with an RF power source (1), so that output impedance (Zo) of the RF power source (1) matches with an impedance (Z L ) of a laser tube (4) that is connected thereto via power transmission means (3). The electric power of radio frequencies generated by the RF power source (1) is effectively supplied to the laser tube (4) arranged in a laser emitting unit (6), and a laser beam is stably emitted from the laser tube 14) maintaining high efficiency.

    摘要： Laser apparatus includes a plurality of metal segments 2 distributed along a tube 1, the end electrodes 2a and 2b being connected to respective plates of a capacitor 9, and the segment 2c adjacent to one of the end segments being arranged to act as a control electrode. During operation, the control electrode is held at a fixed bias potential and a large potential difference is applied between electrodes 2a and 2b. When it is desired to trigger a discharge within the tube 1, a trigger potential is applied to the control electrode 2c. Power dissipated in repetitive discharges so formed vaporises or dissociates material 6 located within the tube 1 and provides pumping power whereby laser action is achieved.
    In another embodiment (not shown) an electron beam is introduced within the tube to trigger the discharge.

    摘要： Improved laser power supply designed to provide the high electric field required for starting a laser. This invention has the capability of automatically readjusting after laser action is initiated to provide an optimum impedance match for high efficiency energy transfer. As shown in (Fig. 1), the invention includes variable means (21) for matching the impedance of a laser cavity (14) with a source of RF energy (12). In addition, means (16) are provided for sensing a change in the impedance of the laser cavity. The additional circuitry (32-46) utilizes the sensed change to vary the impedance of the matching elements (50 & 52) to provide and maintain an optimal coupling between the laser cavity (14) and the RF source (12).

    摘要： A laser waveguide (1), where the laser waveguide (1) can be formed by electrodes (2 and 4) and at least one sidewall (3a-d) in a manner allowing a more compact structure than previously provided. Protrusions in the electrodes (2 and 4) allow easier laser starts, and sectional sidewall(s) allow easier fabrication of sidewall(s), decreasing manufacturing costs.
