“…As a result the continuum threshold shifts up by U p as well (see Fig. 2), which is a well-known effect in multiphoton ionization experiments [57]. This upshift is important for the TBR process since free electrons will now have to lose an additional energy U p in order to recombine with an ion.…”

“…is shorter than the time it takes a photoelectron to leave the interaction volume, typically  pulse < 1ps) the absolute position of ATI peaks in the PES depends on the value of the ponderomotive energy U p [2] and therefore on the laser intensity where n is the minimum number of photons with energy ω necessary to overcome the ionization potential IP, and s=0,1,2… is the number of photons absorbed by the atom above the ionization threshold and consequently the number of the ATI order. I laser is the peak intensity of the laser pulse, A max is the maximum of the vector potential.…”

“…Rather, ionization is due to single-photon absorption. (ii) Ponderomotive effects [10] are completely negligible with quiver amplitudes of ∆x ≈ 0.0003 . .…”
