“…We report here a triggering method based on a capacitively coupled (pulsed corona) discharge as UV source [5,6], which distributes the single closure discharges over the electrode surfaces (with plane-parallel geometry) of a simple switch, when working repetitively. The erosion rate of the electrodes is consequently reduced compared with that experienced with the above-mentioned switches, thus giving the potential for long-lifetime operation.…”

A high-voltage gaseous-switch triggering method based on a capacitively coupled (pulsed corona) discharge is described. The method enables the single closure discharges of the switch to be distributed over a large area of the electrodes' surface, yielding a relatively low erosion rate. Therefore, long-lifetime operation of the switch without maintenance is obtained. The switch was tested by discharging a 7.5 nF capacitor at repetition frequencies up to 50 Hz. The maximum voltage was 17 kV with a current peak of about 6 kA.

Instrum.Pulsed transverse electric (TE) glow discharges used to produce population inversions in gas lasers at l-20 atm require high-speed, high-voltage, high-current capacitor banks. In this article we first review and compare the circuits in common use to produce the required fast, self-sustained glow discharges in CO*, excimer, and N2 lasers. The parameters and circuit types given will be useful to future designers of pulsed gas lasers to design and to optimize any proposed circuit in order to yield any desired operating conditions and parameters. The n-stage circuit types presented are capacitor-transfer (C-C), L-C inversion, Marx bank, 'and fourfold L-C inversion, with their double-sided counterparts, and also their transmission-line counterparts, such as the Blumlein circuit. A one-parameter differential equation is developed which describes the general series C-L-R circuit. Electrical pulses measured on various lasers are compared with the differential equation solutions for various bank impedances and load resistances. We then present the design and measurements of a new automatically preionized, double-sided, L-C inversion circuit for an 8OO-mJ, TE CO2 laser, and compare it to previous systems. Methods to lengthen the discharge pulse, and some novel active mode locking techniques are discussed. We compare the L-C inversion circuit, the fourfold L-C inversion circuit, the conventional Marx bank, and the "double Marx bank" for lasers and other applications, such as pulsed particle accelerators. Finally, we discuss capacitor bank interconnections, electro-optic probe systems, and various triggering methods.

Studies on a capacitively coupled discharge applied to a TEA N₂laser

Abstract: The authors report studies on a capacitively coupled discharge which effectively stabilizes the main discharge in a TEA N2 laser excited by Blumlein pulsers. The separation between the driver electrode and the grounded section of the circuit is a critical factor for the stabilizing effect.
