Laser Micro Gap Cutter

A laser beam is used to cut slots under. 0002" wide in a variety of metals and ceramics.

The beam from laser crystal 1 is focused by lens 2 onto the work 3. The work 3 is clamped to rotating table 4 having shaft 5 which is rotated by motor 6 and associated drive 7. Transducer 8 senses when the work is in the proper position and then triggers the laser pulse. During the pulse, the work to be cut is moved to generate a line cut.

An advantage of this technique is that it permits a slot to be cut using a focused spot. Producing a rectangular laser beam image entails the use of aspheric lenses which cannot readily be made to the necessary precision. Relative motion between the spot and work also permits vaporized material to be expelled without interfering with the laser beam. Material hardness is of no consequence as metals and ceramics are cut with equal ease.
