Laser sublimation-drilling in flat capillaries

If it is about the drilling of small holes into thin wall thicknesses, conventional drilling reaches its limits. Getting over them, we use laser drilling. During the process a rounded cutting edge comes up owing to the vaporization of the glass, which makes the drilling mechanical unsusceptible. Shown here, little holes with a diameter under 1 mm were drilled in the sidewalls of a flat capillary.
