Abstract
Apparatus and processes are utilized to pierce holes in a brittle material by the use of laser induced shock waves. The waves are generated in an environment of compressed gas which confines the shock wave and carries the debris away. The material is moved into and/or through the work area in the y-direction either by a supporting web with associated rollers or sliding action. The laser beam scans in the x-direction and computer control is utilized to either deflect a continuous beam or switch a pulsed beam 'on' where a hole is desired in the material.
