Microstructuring glass comprises focussing lasers on various volume elements in the glass at a temperature above the transformation temperature of the glass melt

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method for creating microstructures within glass by focusing lasers on specific regions while the glass is heated above its transformation temperature. The process causes local gas bubble formation due to changes in gas solubility, and when the glass cools, these bubbles remain, forming precise microstructures within the glass.

Patent Abstract

Microstructuring glass comprises focussing lasers on various volume elements in the glass at a temperature above the transformation temperature of the glass melt, whereby the temperature-dependent gas solubility in the melt is locally exceeded (i.e. gas bubbles are formed), which creates a microstructure on cooling.
