Longitudinal-discharge-pulse laser with preionization obtained by corona effect
Patent
·
OSTI ID:5382677
A longitudinal-discharge-pulse laser has two coaxial sections in the form of glass tubes joined together by a grounded central electrode and terminated by two outer electrodes. Each glass tube carries on its outer surface a multiplicity of metal rings connected in parallel, via a step-up transformer, to the anode of a first thyratron for energization with a steep negative pulse to generate a corona effect for the preionization of a gas mixture in the tubes on command of a pulse-cadence generator. This generator also controls a second thyratron, with a predetermined delay, which applies negative trigger pulses to the two outer electrodes for initiating a pumping discharge of the laser.
