Autor: Genieys, T, Petrakakis, M, Tsibidis, G, Sentis, M, Utéza, O

Publikováno v: Journal of Physics D: Applied Physics, IOP Publishing, 2021, 54 (49), pp.495302

The optical response of nickel is studied in a wide range of laser fluence, below and above the ablation threshold, by selfreflectivity measurements of ultrashort 800nm single laser pulses. At the ablation threshold, the reflectivity remains unchange

Report

Investigation of ultrashort laser excitation of aluminum and tungsten by reflectivity measurements

Autor: Genieys, T., Sentis, M., Utéza, O.

Publikováno v: Applied physics. A, Materials science & processing, Springer Verlag, 2020, 126 (4)

We determine the laser-induced ablation threshold fluence in air of aluminum and tungsten excited by single near-infrared laser pulses with duration ranging from 15 fs to 100 fs. The ablation threshold fluence is shown constant for both metals, exten

Report

Material decomposition mechanisms in femtosecond laser interactions with metals

Autor: Povarnitsyn, M. E., Itina, T. E., Sentis, M., Khishchenko, K. V., Levashov, P. R.

A numerical hydrodynamic study of femtosecond laser ablation is presented. A detailed analysis of material decomposition is performed using a thermodynamically complete equation of state with separate stable and metastable phase states and phase boun
