Title: Laser amorphisation of glass ceramics: basic properties and new possibilities for manufacturing microoptical elements

Abstract

The laser amorphisation of glass ceramics (LAGC) is studied by optical pyrometry and video recording. The mechanism of local LAGC as a structural phase transition determined by the temperature kinetics in the laser-irradiated region is proposed. The ranges of the power density and exposures to the 10.6-{mu}m IR radiation required for amorphisation of the typical glass ceramics, a SiO{sub 2}-Al{sub 2}O{sub 3}-CaO-MgO-TiO{sub 2} sital are determined. It is shown that LAGC can be used to fabricate a number of miniature optical elements such as lenses, lens rasters, light guides and waveguides, etc. (laser technologies)
