摘要
Fabrication of deep high-quality holes in different materials is required for many industrial applications. In this presentation we provide results of detailed investigations on deep drilling of metals by femtosecond laser pulses. We identify most important parameters which should be fulfilled for the fabrication of high-quality holes and efficient femtosecond laser ablation, discuss the role played by the laser-induced optical breakdown, debris, and laser pulse repetition rate.
