Abstract

Uniformity and stability of discharge process in a high Pulse Repetition Frequency (PRF) long pulse XeCl laser are investigated for three different cathode materials (aluminium, copper, brass) versus PRF (f <EQ 700 Hz) and burst duration (1 - 100 shots). The discharge quality evolution is experimentally studied with a fast gated CCD video camera providing 200 - 400 ns time-integrated discharge photographs. This discussion also benefits from a theorical approach of the macroscopic properties of the different cathode materials and from the development of a simple code calculating the shot to shot electrode temperature increase due to the successive input energy releases.
