Abstract

Laser drilling of engineering materials is well established process. Latest developments in laser sources offer enormous flexibility but also present challenges. Laser material interaction governs the material removal process and correct laser parameters are key to successful processing. New generation fiber lasers offer 25 different pulse shapes/durations ranging from 15ns up to 220 ns. Those different waveforms offer different pulse energies as well. The paper discusses effect on the green ceramic tapes when processed with various pulse lengths/shapes in terms of resulting diameter, accuracy and quality
