Abstract
A gas laser arrangement includes a discharge tube between a cathode and an anode, the discharge tube including a central discharge channel and at least one gas return channel. A blocking electrode is provided at the openings of the gas return channels at least in the cathode space and possibly also in the anode space, the blocking electrode being connected to a blocking voltage to avoid misfirings of the laser through the gas return channels.
