Abstract:
A narrow band excimer laser apparatus includes a line narrowing module that narrows the spectral line width of laser light, a nitrogen gas introducing unit, a first valve that restricts the flow of nitrogen gas from the introducing unit into a casing of the module, an exhaust unit that causes gas to flow out from the casing, an exhaust pump for exhausting the gas from the casing, a second valve that restricts the exhausting of gas from the exhaust unit, an atmosphere discharge unit that discharges the gas within the casing into the atmosphere, a third valve that restricts the discharge of gas into the atmosphere, and a control unit that closes the second valve while opening the first and third valves, supplies nitrogen gas into the casing, then closes the third valve while opening the first and second valves, drives the exhaust pump, and causes laser oscillation thereafter.

Claim (Index 15):
The narrow band excimer laser apparatus as defined in  claim 9 , wherein:\n the first valve is a normally open type valve, and the second valve and the third valve are normally closed type valves.
