“…For pulse duration down to a few picoseconds or even to some hundred femtoseconds, the laser ablation processes take place through phase explosion of a superheated melt layer with subsequent ejection of nano-sized particles and negligible thermal damage to the surrounding bulk material [2,3]. Besides the pulse duration, the laser fluence, the beam polarization, and the repetition rate are also relevant [4][5][6][7]. However, heat accumulation effects during pulsed laser irradiation at relatively high repetition rates (several hundred kHz) and pulse energies may still cause the generation of some amount of molten material, which is detrimental to the quality of the laser ablation [8][9][10].…”
