摘要： Four broad metal vanes form two pairs of contoured metal sheets arranged symmetrically about orthogonal planes of a discharge device to provide a uniform and properly shaped electric field for a discharge region between opposed slab electrodes situated between upper and lower pairs of the vanes in proximity to electrode edges. The electrodes border the region inside a housing having dielectric wall portions interposed between broad surface portions of the vanes and the discharge region located intermediate the electrodes. The electric field is delineated by the vanes so as to inhibit discharge tracking on the wall portions bounding the discharge region.

摘要： Apparatus for establishing and maintaining a stable discharge across a stream of flowing gas, particularly useful for high-power lasers, comprises working electrodes disposed on opposite sides of the gas flow channel, and starting electrodes adjacent to the upstream working electrodes. Each working electrode includes a ballast impedance and is connected between a high-voltage source and a point of fixed reference potential. Each starting electrode includes a substantially larger ballast impedance and is connected to the point of fixed reference potential such that each starting electrode is effective to bring the point of fixed reference potential to the upstream working electrode to start the discharge, and to draw little current after the discharge has been started.

摘要： Apparatus for establishing and maintaining a stable electrical discharge across a stream of gas flowing through a gas flow channel, particularly useful in high-power lasers, comprises a plurality of modular elements each including a plurality of electrodes, a ballast impedance for each electrode, and a cooling element for each electrode in thermal communication with the electrode and its ballast impedance, all embedded within a block of insulating material. The ballast impedances for the electrodes at the downstream side of the gas flow channel have lower impedance values than those for the electrodes at the upstream side of the channel so as to compensate for the lower impedance of the gas flowing through the channel at the downstream side and to produce a substantially constant voltage across the various portions of the channels.

摘要： A pair of electrodes for producing a very uniform electric field within a predetermined region. The electrodes have a special theoretically-derived shape which inherently terminates the electrodes just outside the predetermined region, thereby overcoming any need to empirically truncate the design to achieve compactness and low inductance. In contrast to conventional truncated designs, the performance of electrodes shaped according to the present invention is analytically predictable, thereby minimizing the need for time-consuming experimentation.

摘要： The laser comprises a gas-filled channel (51) extending between a pair of metal plates (2 and 3). The laser is excited by a spark discharge through the gas from one plate to the other. The energy for the spark comes form a pair of built-in capacitors extending between the plates on either side of the channel. The plates constitute the plates of the capacitors, and apart from a plastic retaining wall (37, 39) round each capacitor, the capacitor dielectric is water. The water is advantageously pumped (47) round a cooling circuit (48), and it is not permanently damaged if an accidental discharge takes place through the water. The invention is particularly applicable to nitrogen and to excimer lasers.

摘要： The present invention is an improved laser bore and electrode structure including an elongated chamber for use in combination with a gas laser within which a laser gas is disposed. The laser also includes first and second reflectors which reflect light energy from the laser gas discharge within the elongated chamber so that the light energy travels longitudinally the length of the elongated chamber and first and second electrodes which transversely excite the laser gas. Each of the electrodes is formed from an electrically conductive material and they are disposed opposing each other. An energy generator applies a voltage of alternating polarity between the first and second electrodes at a frequency ranging from 10 Mhz to about 3 GHz to establish a laser gas discharge in the laser gas. A coupling network matches the steady state impedance of the elongated chamber to the impedance of the energy generator and couples the first electrode to the second electrode in order to cancel the pre-ignition reactive impedance of the elongated chamber, the first impedance-matching network coupling the first and second electrodes and the second impedance-matching network to the energy generator. The improved laser bore and electrode structure includes an elongated chamber which is in the shape of a four pointed star and which is of cross-sectional dimensions suitable for confining a laser gas discharge. The elongated chamber is formed from a dielectric material.
