Infrared spectra in amorphous alumina: a combined ab initio and experimental study
L. Giacomazzi, N. S. Shcheblanov, M. E. Povarnitsyn +5
We present a combined study based on experimental measurements of infrared (IR) dielectric function and first-principles calculations of IR spectra and vibrational density of state…
Generation of keV hot near-solid density plasma states at high contrast laser-matter interaction
O. N. Rosmej, Z. Samsonova, S. Höfer +13
We present experimental evidence of ultra-high energy density plasma states with the keV bulk electron temperatures and near-solid electron densities generated during the interacti…
Nonlinear photoionization of transparent solids: a nonperturbative theory obeying selection rules
N. S. Shcheblanov, M. E. Povarnitsyn, P. N. Terekhin +2
We provide a nonperturbative theory for photoionization of transparent solids. By applying a particular steepest-descent method, we derive analytical expressions for the photoioniz…
Implementation of kinetics of phase transitions into hydrocode for simulation of laser ablation
Mikhail E. Povarnitsyn, Pavel R. Levashov, Konstantin V. Khishchenko
We model an interaction of femtosecond laser pulses (800 nm, 100 fs, 1-100 TW/cm) with metal targets (Al, Au, Cu, and Ni). A detailed analysis of laser-induced phase transition…
Suppression of ablation in femtosecond double pulse experiments
M. E. Povarnitsyn, T. E. Itina, K. V. Khishchenko +1
We report the physical reasons of a curious decrease in the crater depth observed for long delays in experiments with femtosecond double pulses. Detailed hydrodynamic modeling demo…
Modeling of optical, transport, and thermodynamic properties of Al metal irradiated by intense femtosecond laser pulses
Konstantin V. Khishchenko, Mikhail E. Veysman, Nikolay E. Andreev +3
A theoretical model is developed for the interaction of intense femtosecond laser pulses with solid targets on the basis of the two-temperature equation of state for an irradiated…
