Pulsed electric discharge laser utilizing water dielectric blumlein transmission line
A pulsed electric discharge gas laser driven by a folded blumlein transmission line with liquid dielectric is described. A method of preionizing and firing the laser discharge utilizing the blumlein voltage pre-pulse for preionization and the subsequent main voltage pulse for gap switch breakdown. A spark gap switch construction with first and second elongate electrodes, with the first electrode presenting a generally rounded surface to the second electrode which incorporates a thin continuous edge facing the first electrode. An elongate apertured cathode at the lasing chamber, with an elongate preionization electrode positioned behind the cathode, and a power supply providing a preionization electrical pulse across the cathode and preionization electrode producing ions and electrons in the lasing gas prior to the main discharge between the anode and cathode.
