Multicolor XUV above threshold ionization of Argon
(IOP Publishing, 2015-10-23)
Argon photo-electron spectra produced by short-pulse extreme ultraviolet radiation, and with particular emphasis on the two-photon absorption region, is analyzed theoretically. The electromagnetic pulse is modeled to ...
Ionization of argon by two-color laser pulses with coherent phase control
(American Physical Society, 2015-08)
We present a joint experimental and theoretical study of ionization of argon atoms by a linearly polarized two-color laser field (800 nm, 400 nm). Changing the relative phase between the two colors, the forward-backward ...
Signatures of tunneling and multiphoton ionization by short-laser pulses: The partial-wave distribution
(Institute of Physics Publishing, 2015-12)
We analyze the two-dimensional angular momentum-energy distribution of electrons emitted from argon by short laser pulses. We identify characteristic features of both multiphoton and tunneling ionization in the partial-wave ...
Laser-assisted photoionization: Streaking, sideband, and pulse-train cases
(American Physical Society, 2020-10)
We present a theoretical study of atomic laser-assisted photoionization emission. We consider an atom driven by a linearly polarized extreme ultraviolet laser in two scenarios: (i) a single attosecond pulse (in both the ...
Signatures of tunneling and multiphoton ionization in the electron-momentum distributions of atoms by intense few-cycle laser pulses
(American Physical Society, 2006-12)
Electron-momentum distributions for above-threshold ionization of argon in a few-cycle, linearly polarized laser pulse are investigated. Spectral features haracteristic of multiphoton as well as tunneling ionization coexist ...
Three-dimensional morphology of rigid structures as a tool for taxonomic studies of Dactylogyridae (Monogenea)
Dactylogyridae is overwhelmingly the most abundant and diverse taxon among monogeneans in continental waters of South America. Their small body size requires considerable sampling effort and training for collecting and ...
Above-threshold ionization driven by few-cycle spatially bounded inhomogeneous laser fields
(IOP Publishing, 2020-02-27)
In this work, we study the main features of the photoelectrons generated when noble gas atoms are driven by spatially bounded inhomogeneous strong laser fields. These spatial inhomogeneous oscillating fields, employed to ...
Structure and photochemistry of a novel tetrazole-saccharyl conjugate isolated in solid argon
(Elsevier Science, 2012-10)
A combined matrix isolation FTIR and theoretical DFT/B3LYP/6-311++G(3df, 3pd) study of the novel synthesised tetrazole-saccharyl conjugate 2-[1-(1H-tetrazol-5-yl)ethyl]-1,2-benzisothiazol-3(2H)-one 1,1-dioxide [1-TE-BZT] ...
Pulsed laser-induced effects in the material properties of tungsten thin films
