Paper Abstract

A commercial Lambda 248 L excimer system has been equipped with a newly developed wavemeter. The self-controlling laser system can be stabilized at a pre-selected wavelength in the range of 248.180 to 248.580 nm with an absolute accuracy of ± 0.001 nm. Due to the deep-UV stepper optics the wavelength can be adjusted absolutely to comply with different optics. The modified 248 L-system can be operated at an average power of up to 5 W. Experimental results are presented.
