Abstract

Discharge instabilities in F2 based excimer gas lasers are investigated using a small-scale discharge system. After preionizing the gas volume, a fast rising voltage pulse initiates the discharge. The temporal development of the discharge is monitored via its fluorescence by an intensified CCD camera with a gating time of 10 ns. Homogeneous discharges are produced in gas mixtures of He/1mbar F2 and He/1mbar F2/30mbar Xe at a total pressure of 2 bar for pump pulse duratins up to 70 ns (FWHM). The addition of Xe to He/F2 mixture does not lead to discharge instabilities while the introduction of more F2 results in hotspot and filament formation.
