Optical Probing of Ultrafast Laser-Induced Solid-to-Overdense-Plasma Transitions
Yasmina Azamoum, Georg Alexander Becker, Sebastian Keppler +11
Understanding the target dynamics during its interaction with a relativistic ultrashort laser pulse is a challenging fundamental multi-physics problem involving at least atomic and…
Control of nonlinear processes using versatile random photonic sources: Application to the energy deposition in a dielectric material
Denis Marion, Jean-Christophe Delagnes, Guillaume Duchateau
We report on the properties of a non-conventional stochastic photonic source. We first describe the principle of nonlinear intensity filtering by using a modified Mach-Zehnder inte…
Direct-drive measurements of laser-imprint-induced shock velocity nonuniformities
J. L. Peebles, S. X. Hu, W. Theobald +8
Perturbations in the velocity profile of a laser-ablation-driven shock wave seeded by speckle in the spatial beam intensity (i.e., laser imprint) have been measured. Direct measure…
Attenuation of slow Metal-Insulator-Metal plasmonic waveguides, from Joule absorption to roughness-induced backscattering
Stephane Coudert, Guillaume Duchateau, Stefan Dilhaire +1
By combining analytical and numerical approaches, we theoretically investigate the effect of fabrication imperfections, e.g. roughness at metal interfaces, on nanometer metal-insul…
Maxwell-consistent, symmetry- and energy-preserving solutions for ultrashort laser pulse propagation beyond the paraxial approximation
P. González de Alaiza Martínez, G. Duchateau, B. Chimier +4
We analytically and numerically investigate the propagation of ultrashort tightly focused laser pulses in vacuum, with particular emphasis on Hermite-Gaussian and Laguerre-Gaussian…
Thermo-elasto-plastic simulations of femtosecond laser-induced structural modifications: application to cavity formation in fused silica
Romain Beuton, Benoît Chimier, Jérôme Breil +3
The absorbed laser energy of a femtosecond laser pulse in a transparent material induces a warm dense matter region which relaxation may lead to structural modifications in the sur…
Theoretical derivation of laser-dressed atomic states by using a fractal space
Guillaume Duchateau
The derivation of approximate wave functions for an electron submitted to both a coulomb and a time-dependent laser electric fields, the so-called Coulomb-Volkov (CV) state, is add…
Influence of non-collisional laser heating on the electron dynamics in dielectric materials
L. Barilleau, G. Duchateau, B. Chimier +2
The electron dynamics in dielectric materials induced by intense femtosecond laser pulses is theoretically addressed. The laser driven temporal evolution of the energy distribution…
Filamentation of ultrashort laser pulses in silica glass and KDP crystal: A comparative study
Jérémie Rolle, Luc Bergé, Guillaume Duchateau +1
Ionizing 800-nm femtosecond laser pulses propagating in silica glass and in potassium dihydrogen phosphate (KDP) crystal are investigated by means of a unidirectional pulse propaga…
Coulomb-Volkov approach of ionization by extreme ultraviolet laser pulses in the subfemtosecond regime
Guillaume Duchateau, Eric Cormier, Robert Gayet
In conditions where the interaction betweeen an atom and a short high-frequency extreme ultraviolet laser pulse is a perturbation, we show that a simple theoretical approach, based…
