Paper Abstract

In the present report, plasma formed on the surface of metals and dielectric materials under the action of XeCl and KrCl lasers is studied. Plasma formation thresholds and plasma expansion velocities are measured. It was shown that long-lived plasma objects are formed near a target in the atmosphere of Xe or air at pressure 0.1 - 1 atm. Duration of luminescence of the plasma objects was maximal in xenon. Non-symmetric current passing through the laser plasma and the current interruption were obtained. The interruption time was as short as 10 ns while the plasma resistance increases with the rate up to 1010 Ohm/s. It is shown that the interruption rate increases when plasma of elements with small atomic weight is used and at higher rice-time of the current before its interruption. It was found that the plasma ionization degree is saturated before the interruption. The interruption effect was used for development of generators with inductive energy storages. Generator with a plasma erosion opening switch with opening current of 10 kA operating at pulse repetition rate up to several Hz was used for excitation of pulsed lasers. Using the generator, laser action on nitrogen and XeCl molecules and atomic transition of Ne was obtained.
