As with other laser-processing applications, laser drilling transforms
material by the agency of tightly focusing a high intensity beam of light onto the
surface of the workpiece at power densities sufficient to either dissolve
or vaporize the material.

Laser drilling has rest successful manufacturing applications in
the automotive, aerospace, efficacy electronics, medical, and consumer
good industries. Lasers make it possible to machine actual small holes,
unusually shaped perforations and precisely tapered holes. They are used
to drill apertures at steep angles, and to proces difficult-to-machine
