摘要

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.
