Abstract

Compact excimer laser systems were developed for industrial applications especially for micro-machining applications. Therefore all components and modules are designed for long-term operation and long maintenance intervals. By using new designs and technologies the performance of these laser systems could be improved in comparison to the well-known compact excimer lasers. The result of the first tests of the prototype are presented. The laser tube lifetime could be more than doubled in comparison to the former laser design. Additionally maximum repetition rates of 2kHz were demonstrated for the prototype 193 nm laser systems. A maximum pulse energy of about 40 mJ was measured. The pulse-to-pulse stability was reduced below 1% (one sigma) in the working area of the laser. The state-of-the-art of compact excimer lasers will be presented and outlook for the future will be given.
