    摘要: A laser apparatus includes a chamber accommodating a pair of discharge electrodes, a gas supply and exhaust device configured to supply laser gas to an interior of the chamber and exhaust laser gas from the interior of the chamber, and a controller. The controller performs first control to control the gas supply and exhaust device so as to suspend laser oscillation and replace laser gas in the chamber at every first number of pulses or first elapsed time, and second control to control the gas supply and exhaust device so as to suspend laser oscillation and replace laser gas in the chamber before the first control at every second number of pulses less than the first number of pulses or second elapsed time less than the first elapsed time.

    摘要: An extreme ultra violet light source apparatus in which debris moving within a chamber are prevented from reducing reflectance or transmittance of optical elements of an EUV collector mirror, etc, and extreme ultra violet light can stably be generated in a long period. The apparatus includes: a target supply unit for supplying a target to a predetermined position within a chamber; a driver laser for applying a laser beam to the target to generate first plasma; a collector mirror provided within the chamber, for collecting extreme ultra violet light radiated from the first plasma; a gas supply unit for supplying a gas into the chamber; an excitation unit for exciting the gas to generate second plasma around a region where the first plasma is generated; and an exhaust unit for exhausting the chamber and ejecting debris emitted from the first plasma to outside of the chamber.
