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 r_B and processing time t_p.
