    "abstract": "Femtosecond laser ablation of Ti, Zr and Hf has been investigated by means of\nin-situ plasma diagnostics. Fast plasma imaging with the aid of an intensified\ncharged coupled device (ICCD) camera was used to characterise the plasma plume\nexpansion on a nanosecond time scale. Time- and spaceresolved optical emission\nspectroscopy was employed to perform time-of-flight measurements of ions and\nneutral atoms. It is shown that two plasma components with different expansion\nvelocities are generated by the ultra-short laser ablation process. The\nexpansion behaviour of these two components has been analysed as a function of\nlaser fluence and target material. The results are discussed in terms of\nmechanisms responsible for ultra-short laser ablation.",
