Abstract
A method for processing glass is provided. The method includes the steps of providing a glass element and removing glass material from the glass element by etching with an alkaline etching medium in an organic solvent.
Claims21
A method for processing glass, comprising:
- providing a glass element;
- and
- removing glass material from the glass element, wherein the removing step comprises:
- introducing filament-shaped flaws into the glass element along a prescribed path with a laser beam of an ultrashort pulse laser having pulse duration less than 100 ps;
- and
- expanding the flaws in the glass element by etching with an alkaline etching medium in an organic solvent to form channels,
- wherein the alkaline medium contains water mainly due to ambient humidity.

A method for processing glass, comprising:
- providing a glass element;
- and
- removing glass material from the glass element, wherein the removing step comprises:
- introducing filament-shaped flaws having a diameter of at most 1 μm into the glass element along a prescribed path with a laser beam of an ultrashort pulse laser having a pulse duration less than 100 ps;
- and
- expanding the filament-shaped flaws in the glass element by etching with an alkaline etching medium in an organic solvent to form channels, wherein the alkaline etching medium has a water content mainly due to ambient humidity and the organic solvent comprises an alcohol.
