TL;DR: The laser-triggered switching (LTS) of highvoltage spark gaps is considered in this paper, which predicts dependencies of the delay to breakdown and switching jitter on such variables as fill gas mixture and pressure, gap spacing, polarity, and geometry.
Abstract: The laser-triggered switching (LTS) of high-voltage spark gaps is considered. The basic theory is presented which predicts dependencies of the delay to breakdown and switching jitter on such variables as fill gas mixture and pressure, gap spacing, polarity, and geometry. It is shown that electrical arcs of several metres length can be directed by laser action. A complete set of experiments is reported which adequately support the proposed theory. The performance of LTS is considered and results are reported on multiple gap triggering, multiple channel triggering, triggering of voltages in excess of 3 mV, repetitive switching at rates up to 50 pps with subnanosecond jitter, as well as various geometries, pulse forming demonstrations, and output voltage selection on a Marx generator.

Journal ArticleDOI
TL;DR: In this article, a novel excitation technique is described for molecular gas lasers, where a specially constructed electrode configuration is activated by a rapid Marx generator, and a very homogeneous self-sustained discharge can be obtained although no separate preionization source is present.

TL;DR: In this paper, it was shown that in the case of small systems, it is possible to obtain a sufficiently fast discharge from a Marx generator only by using a small number of pulses with high current densities.
Abstract: Vacuum ultraviolet stimulated emission of high intensity was obtained in the past by the transverse pumping of high-pressure noble gases by means of high-current relativistic electron beams. The main interest for such laser systems is their potential for obtaining high output powers with high efficiency. In general the lifetime of the upper state of these lasers is in the order of nanoseconds, so that very fast pumping is required. So far it has been reported that short pulses with high current densities were obtained by Blumlein or pulse-line circuits. From a technical point of view such a system is expensive and rather complicated. Therefore one may wonder whether in the case of small systems it is possible to obtain a sufficiently fast discharge from a Marx generator only. This is the main point of the present contribution.

TL;DR: In this paper, the authors applied a coaxial Marx generator with the rectangular pulse across a constant load for a study of double focusing diodes and found an important difference of the behavior between the single and double focusing diode.
Abstract: Applying a coaxial Marx generator with the rectangular pulse across a constant load for a study of double‐focusing diodes, an important difference of the behavior between the single‐ and the double‐focusing diode is found. In order to understand its behavior more precisely, the necessity will be pointed out to take into account the anode plasma effects.
