Numerical Study of the Wetting Dynamics of Droplet on Laser Textured Surfaces: Beyond Classical Wenzel and Cassie-Baxter Model
Ilemona S. Omeje, Tatiana E. Itina
The classical wetting models, such as the Wenzel and Cassie-Baxter have been extensively used to quantify the wettability of laser-textured surfaces. However, these models do not p…
Plume dynamics and nanoparticle formation in ultra-short laser ablation of metals
T. E. Itina
Nanoparticle formation by femtosecond laser ablation is investigated for different experimental conditions. Dynamics of the laser plume expansion is visualized based on numerical s…
Rippled area formed by surface plasmon polaritons upon femtosecond laser double-pulse irradiation of silicon: the role of carrier generation and relaxation processes
Thibault J. -Y. Derrien, Jörg Krüger, Tatiana E. Itina +3
The formation of laser-induced periodic surface structures (LIPSS, ripples) upon irradiation of silicon with multiple irradiation sequences consisting of femtosecond laser pulse pa…
Possible surface plasmon polariton excitation under femtosecond laser irradiation of silicon
Thibault J. -Y. Derrien, Tatiana E. Itina, Rémi Torres +2
The mechanisms of ripple formation on silicon surface by femtosecond laser pulses are investigated. We demonstrate the transient evolution of the density of the excited free-carrie…
Application of a two-temperature model for the investigation of the periodic structure formation on Si surface in femtosecond laser interaction
Thibault J. Y. Derrien, Thierry Sarnet, Marc Sentis +1
We consider the case of surface irradiation by a small number of femtosecond laser shots leading to the formation of surface ripples. To explain this effect, we propose a numerical…
Formation of femtosecond laser induced surface structures on silicon : insights from numerical modeling and single pulse experiments
Thibault J. Y. Derrien, Rémi Torres, Thierry Sarnet +2
Laser induced periodic surface structures (LIPSS) are formed by multiple irradiation of femtosecond laser on a silicon target. In this paper, we focus and discuss the surface plasm…
Material decomposition mechanisms in femtosecond laser interactions with metals
M. E. Povarnitsyn, T. E. Itina, M. Sentis +2
A numerical hydrodynamic study of femtosecond laser ablation is presented. A detailed analysis of material decomposition is performed using a thermodynamically complete equation of…
Analyses of femtosecond laser ablation of Ti, Zr, Hf
D. Grojo, J. Hermann, S. Bruneau +1
Femtosecond laser ablation of Ti, Zr and Hf has been investigated by means of in-situ plasma diagnostics. Fast plasma imaging with the aid of an intensified charged coupled device…
