Abstract :
A 1 kHz operation for an ArF excimer laser has been achieved with a compact laser system. The average output power and the electrical efficiency are 13 W and 0.83%, respectively. The clearing ratio is measured to be 3.2. A spectrally narrowed ArF excimer laser for lithography experiments has also been developed on the basis of the design for the compact ArF excimer laser. A spectral bandwidth of 0.7 pm and a pulse energy of 5 mJ/pulse is obtained
