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)
