Paper 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 irrdiation for amorphization of a typical glass-ceramic (GC) α-TiO2 • 2MgO • 2Al2O3 • 5SiO2 is defined. It is demonstrated that a wide range of miniature optical components such as lenses, lenslet arrays, waveguides, geodesic (plane) lenses, etc... can be fabricated by LAGC.
