Paper Abstract

Since 1972 solid state lasers are used as an industrial tool for drilling holes of precision in ruby and ceramics substances /1,2/. In achieving the standard of spark erosive removal of material the laser is superior in metal-working by higher processing velocities. Deviation from roundness and cylindricity are below 5% and the roughness of the hole surface is less than 5 μm for the erosive process. These tolerances are reached in laser material processing within accurate knowledge and control of the processing and laser parameters Intensity I, beam radius rB and processing time tp.
