AB  - Single-pulse microprocessing of a steel surface with a variable pulse width (0.3-12.3 ps) and a wavelength of 515 nm was performed. The morphology of the craters was visualized by a scanning electron microscope and an optical profilometer. The nonmonotonic behavior of ablation thresholds with a minimum at ≈1.5 ps, due to achieving the electron-phonon relaxation time of the absorbed energy in the steel was revealed. It is shown that, with an increase in the pulse width in the considered width range, the efficiency of the ablation decreases by a factor of 2, which is explained by the partial transition from the phase explosion to the surface evaporation. © 2019 Astro Ltd.

AB  - Single-shot femtosecond laser ablation of Ti(Al/Ti)(5) and (Ni/Ti)(5) films on silicon substrates was studied as a function of laser fluence by means of scanning electron microscopy, energy-dispersive x-ray spectroscopy, and optical profilometry. Ablation occurs as gradual threshold-like selective removal of a few top layers at lower fluences and rather continuous removal at higher fluences, exponentially increasing versus ablated depth, with the final complete (through) ablation of the entire films. The observed selective rupture at the different internal interfaces was related to thermomechanically and chemically enhanced (interface-facilitated) explosive boiling, with the corresponding energy deposition provided by cascaded heat transfer in the poorly conducting Ti and Ni, and highly conducting Al layers and the interfacial thermal (Kapitza) resistance effect.
