Removing material from workpieces involves feeding laser beam into water surrounding removal point at angle to normal to water level via optical window beneath water level

摘要

The method involves using a pulsed laser beam, whereby the laser beam (14) is directed onto a point of material removal on the workpiece (10) surrounded by water. The laser beam is fed into the water surrounding the removal point at an angle to the normal (21) to the water level via an optical window (16) beneath the water level (111). Independent claims are also included for the following: an arrangement for removing material from workpieces.
