Machining Grooves in Glass


Laser micromachining processes have many advantages. They allow for micro-scale machining and are contact free, which means no surface contamination. In addition, laser welding makes it possible to fabricate components without adhesive for results that are more stable, durable, and shock resistant.

  • 60 µm wide groove at a 16° angle
  • V-groove in a glass substrate etched by CO2 laser
  • Machining grooves in glass
  • Drilling an SMF-28 fiber with a CO2 laser


The fabrication of all-glass devices offers benefits in terms of mechanical and thermal robustness. V-grooves are frequently used to align components, and laser machining is a simple way to produce them. Groove parameters can be adjusted depending on the application.
