Abstract

Laser amorphization of glass-ceramics (LAGC) is investigated by optical pyrometry and video recording. Due to this new knowledge, the mechanism of local LAGC is made clear as a phenomenon leaded by thermal kinetic. The required power density and temporal range of CO₂-laser irradiation for amorphization of a typical glass-ceramic (GC) α-TiO₂• 2MgO • 2Al₂O₃ • 5SiO₂ are defined. Fabrication of a wide range of microoptical components such as lenses, lens arrays, wave-guides, geodesic lenses ... are demonstrated with methods for controlling of their parameters.
