Thermomechanical investigation of silicon wafer dynamics within the melting regime driven by picosecond laser pulses for surface structuring
Helen Papadaki, Inam Mirza, Nadezhda M. Bulgakova +2
Laser-induced periodic surface structures (LIPSS) on silicon, generated by ultrashort pulsed lasers, provide an efficient means to tailor surface functionality. This work presents…
Volumetric glass modification with Gaussian and doughnut-shaped pulses: From localized laser energy absorption to absorption delocalization
Martin Zukerstein, Vladimir P. Zhukov, Yuri P. Meshcheryakov +1
Volumetric modification of glass materials by ultrashort laser pulses is a powerful technique enabling direct writing of three-dimensional structures for fabrication of optical, ph…
On the Melting Thresholds of Semiconductors under Nanosecond Pulse Laser Irradiation
J. Beranek, A. V. Bulgakov, N. M. Bulgakova
In this work, a unified numerical model is used to determine the melting thresholds and to investigate early stages of melting of several crystalline semiconductors (Si, Ge, GaAs,…
Melting of gold by ultrashort laser pulses: Advanced two-temperature modeling and comparison with surface damage experiments
Sergey A. Lizunov, Alexander V. Bulgakov, Eleanor E. B. Campbell +1
The ultrafast laser-induced solid-liquid phase transition in metals is still not clearly understood and its accurate quantitative description remains a challenge. Here we systemati…
Photoionization and transient Wannier-Stark ladder in silicon: First principle simulations versus Keldysh theory
Thibault J. -Y. Derrien, Nicolas Tancogne-Dejean, Vladimir P. Zhukov +3
Nonlinear photoionization of dielectrics and semiconductors is widely treated in the frames of the Keldysh theory whose validity is limited to small photon energies compared to the…
Electronic mechanism of ion expulsion under UV nanosecond laser excitation of silicon: Experiment and modeling
Wladimir Marine, Nadezhda M. Bulgakova, Lionel Patrone +1
We present experimental and modeling studies of UV nanosecond pulsed laser desorption and ablation of (111) bulk silicon. The results involve a new approach to the analysis of plum…
