Microstructuring Glasses by Laser Processing

Silicate glass was textured using a CO2 laser [330]. The texturing is used to fabricate computer discs of high specific information density made from glass substrates. Laser pulses create a nanotexture on a surface of a glass disc. The process is based on rapid thermal cycles to manipulate the transformation temperature and finally the microstructure of the glass in the zone affected by the heat.
