摘要:
A gas laser comprises a discharge channel which is defined by two electrodes located on a dielectric layer spaced from one another. The dielectric layer forms a carrier which has a further electrode on the opposite side thereof. A laser head is connected to one end of this structure and includes a laser active gas encompassing a dielectric plate optically coupled to the discharge channel. The first of the two electrodes extends into the laser head and the last-mentioned electrode wraps around the end of the dielectric plate to the plane of the plane of the first electrode and to a point spaced therefrom to form a gap which is a surface discharge gap. The other end of the structure is connected to a high-voltage pulse generator including a switch operable to connect the two electrodes and generate a rapidly rising voltage pulse. The first of the two electrodes and the further electrode are connected to a reference potential by way of respective inductances.
