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.
