Paper Abstract

The uniformity and stability of discharge process in a high pulse repetition frequency (PRF) long pulse XeCl laser are investigated for three different electrode materials (aluminum, copper, brass) and different roughnesses of the copper electrode versus PRF (f less than or equal to 700 Hz) for burst durations of 10 shots. The discharge quality evolution is experimentally analyzed from discharge photographs obtained with a CCD video camera and pressure perturbation measurements achieved with a piezoelectric pressure probe placed very close to the discharge volume.
