Title: Laser excitation system

Patent ·
OSTI ID:5658324

An excitation system for applying a high voltage source to induce a discharge in a laser medium within a chamber is described comprising: a. at least one capacitor capable of storing an electric pulse from the high voltage source prior to discharge; b. a fixed potential electrode, capable of draining the electric pulse upon laser discharge; c. a floating electrode; d. a laser discharge region defined by a volume between the fixed potential electrode and the floating electrode; e. at least one first spark-inducing element, electrically connected to the high voltage source and the floating electrode, the first spark-inducing element serving to preionize the medium by generating ultraviolet radiation within the chamber during the charging of the capacitor; and f. at least one second spark-inducing element, electrically connected to the floating electrode and the capacitor, the second spark-inducing element serving to likewise preionize the medium by generating ultraviolet radiation within the chamber during the charging of the capacitor and also serving to sustain the generation of ultraviolet radiation within the chamber during laser discharge.
