Abstract

An experimental study is reported of the generation and behavior of discharge-induced shocks and waves in a compact high repetition rate XeCl excimer laser (CHIRP) with helium as buffer gas. Three sources of shocks and waves are identified. Longitudinal shocks are formed at the discharge boundaries, traveling up and downstream into the gas flow duct. A transverse shock is created at the cathode sheath region, and the anode mesh is the source of an expansion wave followed by a compression wave 1.5 microsec later. Transverse shocks can reflect off the cathode, but no reflections off the anode mesh have been observed.
