ABSTRACT:
A laser microdrilling method uses a power laser beam the action of which causes solid workpiece metal to be transformed into both liquid and vapor phases. In order to improve the surface finish and dimensional accuracy of a hole formed, the workpiece is heated to a temperature sufficient to cause both the liquid phase formed directly by the action of the laser beam and the liquid phase caused by the condensation of the vapor phase on the wall of the hole being formed, to be maintained in the liquid state for a period of time long enough to permit the uniform spreading of these liquid phases over the wall of the hole.
