Book excerpt: Femtosecond laser micromachining is a promising technology for micromachining of various engineering materials. The interaction mechanism of femtosecond laser pulses with matter is completely different compared to traditional lasers. This work presents a detailed study on the ablation of common engineering materials in air with femtosecond laser pulses. The single and multi-shot ablation threshold fluence and incubation coefficient of Nickel, SMA, Tungsten, PZT, Copper, Cobalt, Stainless Steel, Iron, Titanium, Brass and Aluminum are evaluated. The morphological changes on the material are discussed along with the identification of gentle and strong ablation phases.
