Title
(EN) RF-EXCITED LASER ASSEMBLY
(FR) ENSEMBLE LASER EXCITÉ PAR RF
Abstract
(EN)
A radio frequency (RF) excited laser assembly includes a pair of opposed electrodes (205, 210) defining an inter- electrode gap (215) and a conductive termination bridge (240, 250) in electrical contact with both electrodes. The termination bridge mechanically supports and positions the electrodes relative to each other and provides a termination impedance for an RF voltage applied to the electrodes. A conical spiral inductor (1400) includes one or more metals windings, and one or more concentric terminals, such that the conical spiral inductor defines an inter-winding spacing sufficient to mitigate ionization of a gas medium between windings. A radio frequency (RF) feed- through assembly (1200) configured to apply an RF voltage to a pair of opposing electrodes (1205, 1210) such that a conductor (1219) is isolated from a metal sleeve (1232) positioned around the conductor by ion sheath discharge barrier.
(FR)
L'invention concerne un ensemble laser excité par radiofréquence (RF) comprenant une paire d'électrodes opposées définissant un espace interélectrode et un pont de terminaison conductrice en contact électrique avec les deux électrodes. Le pont de terminaison supporte et positionne mécaniquement les électrodes l'une par rapport à l'autre et fournit une impédance de terminaison pour une tension RF appliquée aux électrodes. Une inductance en spirale conique comprend un ou plusieurs enroulements en métal, et une ou plusieurs bornes concentriques, de telle sorte que l'inductance en spirale conique définisse un espacement interenroulement suffisant pour atténuer l'ionisation d'un milieu gazeux entre les enroulements. Un ensemble traversée de radiofréquence (RF) est conçu pour appliquer une tension RF à une paire d'électrodes opposées de telle sorte qu'un conducteur soit isolé d'une position de manchon en métal autour du conducteur par une barrière de décharge à gaine ionique.
