Development of gas-discharge lasers using tpi-type pseudospark switches

Technical features and unique properties of TPI-series cold cathode thyratrons (pseudospark switches) used as a high-voltage switches in the excitation systems of excimer lasers and thallium vapors laser are presented. The comparative testing of hot cathode thyratron, triggered spark gaps and TPI-series thyratrons in the excitation system of these lasers was performed.
