Abstract:
A gas laser apparatus may include: a laser chamber connected through a first control valve to a first laser gas supply source that supplies a first laser gas containing a halogen gas and connected through a second control valve to a second laser gas supply source that supplies a second laser gas having a lower halogen gas concentration than the first laser gas; a purification column that removes at least a part of the halogen gas and a halogen compound from at least a part of a gas exhausted from the laser chamber; a booster pump, connected through a third control valve to the laser chamber, which raises a pressure of a gas having passed through the purification column to a gas pressure that is higher than an operating gas pressure of the laser chamber; and a controller that calculates, on a basis of a first amount of a gas supplied from the booster pump through the third control valve to the laser chamber, a second amount of the first laser gas that is to be supplied to the laser chamber and controls the first control valve on a basis of a result of the calculation of the second amount.

Claim (Index 8):
The gas purification system according to  claim 1 , wherein the xenon-adding unit includes a valve.
