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 10):
The gas laser apparatus according to  claim 8 , further comprising an operating characteristic measuring instrument that measures an operating characteristic of laser light that is outputted from the laser chamber,\n wherein the controller controls the fifth control valve on a basis of the operating characteristic.
