The results of the successful laser drilling of 30 – 200 μm in diameter microholes in glass ranging in thickness from 0.1 to 0.8 mm are reported. High-quality holes together with high process performance are achieved by using in the hole piercing process an immersion cooling liquid in contact with the bottom surface of the glass.
