Abstract

This paper experimentally demonstrates that two glass-ceramics (including a photosensitive one) can undergo a reversible structural modification under the action of a CO2 laser. The original glass is converted into a glass-ceramic by using spontaneous or photothermoinduced crystallization, and the glass-ceramic is converted back to the original glassy state under the action of laser radiation. The rates of such structural modifications under laser heating are greater by a factor of 10²−10³ than with standard heating in a furnace. The laser process of structural modification of a glass-ceramic makes it possible to develop and produce new optical micromaterials, components, and devices.
