Beschreibung
Zusammenfassung:	The present invention provides an ultra pure purge system for discharge lasers. The LNP, the output coupler, the wavemeter and selected high voltage components are contained in sealed chambers each having a purge inlet port and a purge outlet port. Purge gas such as N2 is filtered and directed to each of the inlet ports. Gas exiting the outlet ports may be directed to flow monitors having alarms so that any loss of purge will be immediately detected. Purge gas may be exhausted or recirculated.
