摘要： In an excimer laser apparatus in which halogen gas, rare gas and buffer gas are fed into the laser chamber, before laser oscillation, the oscillation stop time is calculated, and, if the calculated oscillation stop time exceeds a prescribed time, the calculated oscillation stop time is used to calculate a feeding amount of mixed gas comprising rare gas or buffer gas, and the mixed gas is fed, prior to laser oscillation, in the calculated feeding amount; stable laser output is thereby obtained from the initial period of laser oscillation.
