Longitudinal discharge pulse laser with pre-ionization obtained by means of corona effect

摘要

Longitudinal discharge pulse laser characterized by the fact that it uses preionization by corona effect, the said laser being essentially constituted by three electrodes of which one is common and two are fed by negative pulses, and in which the said electrodes are joined by two glass tubes within which are produced the two discharges under the command of the thyratron and in which the said pre. ionization is obtained by feeding a high voltage pulse through metal rings placed on the said glass tubes, a delay being established between the beginning of the pre- ionization and the trigger of the main discharge.
