Manipulating Twisted Electrons in Strong-Field Ionization
A. S. Maxwell, G. S. J. Armstrong, M. F. Ciappina +5
We investigate the discrete orbital angular momentum (OAM) of photoelectrons freed in strongfield ionization. We use these `twisted' electrons to provide an alternative interpretat…
Laser-assisted photoionization of argon atoms: streaking, sideband and pulse train studying cases
Renata Della Picca, Marcelo F. Ciappina, Maciej Lewenstein +1
We present a theoretical study of atomic laser-assisted photoionization emission (LAPE). We consider an atom driven by a linearly polarized XUV laser in two different scenarios: i)…
Focal-shape effects on the efficiency of the tunnel-ionization probe for extreme laser intensities
M. F. Ciappina, E. E. Peganov, S. V. Popruzhenko
We examine the effect of laser focusing on the potential of a recently discussed scheme [M.F. Ciappina {\em et al}, Phys. Rev. A 99, 043405 (2019); Las. Phys. Lett. 17, 025301 (202…
