Paper Abstract

The F2 excimer laser emitting at 157 nm have been developed to reliable industrial machines applicable for micro-fabrication. Fluorine lasers are available at various power ratings, with energies between 1 mJ and more than 50 mJ and repetition rates up to 2 kHz. The applications of the F2 lasers presented here are mainly related to the micro-machining of glasses, with a special focus on fused silica. Depending on the applied fluence, fused silica can be processed with 157 nm by material ablation as well as by modifying the optical properties, when the energy density is beyond the ablation threshold. Both techniques qualify the 157 nm for manufacturing optical elements like planar wave guides or grating structures. Furthermore, the wavelength has been tested for micro-fluidic and micro-mechanical structures.
