A continuous-mode quantum-optical representation of finite strong-field laser pulses in free space
Szabolcs Hack, Attila Czirják, Péter Földi
We formulate an energy-consistent quantum-optical representation of finite paraxial laser pulses in free space. The formulation is based on a continuous-mode description and provid…
Wave packet motion in a quantized electromagnetic field: Analytic results
Szabolcs Hack, Béla Gábor Pusztai, Krisztina Joós +3
We investigate the dynamics of a charged particle interacting with a multimode quantized electromagnetic field and obtain an analytic solution for the full electron--field system.…
One-dimensional model potentials optimized for the calculation of the HHG spectrum
Krisztina Sallai, Szabolcs Hack, Szilárd Majorosi +1
Based on the favourable properties of previously used one-dimensional (1D) atomic model potentials, we introduce a novel 1D atomic model potential for the 1D simulation of the quan…
Parametric model for high-order harmonic generation with quantized fields
Ákos Gombkötő, Sándor Varró, Béla Gábor Pusztai +4
A quantum optical model for the high-order harmonic generation is presented, in which both the exciting field and the high harmonic modes are quantized, while the target material a…
Diatomic molecule in a strong infrared laser field: level-shifts and bond-length change due to laser-dressed Morse potential
Sándor Varró, Szabolcs Hack, Gábor Paragi +3
We present a general mathematical procedure to handle interactions described by a Morse potential in the presence of a strong harmonic excitation. We account for permanent and fiel…
Quantum interference in strong-field ionization by a linearly polarized laser pulse, and its relevance to tunnel exit time and momentum
Szabolcs Hack, Szilárd Majorosi, Mihály G. Benedict +2
We investigate the liberation of an atomic electron by a linearly polarized single-cycle near-infrared laser pulse having a peak intensity that ensures tunneling. Based on phase sp…
Reconstruction of tunnel exit time and exit momentum in strong field ionization, based on phase space methods
Szabolcs Hack, Szilárd Majorosi, Mihály Benedict +1
We analyze tunnel ionization of a single atom based on the Wigner function over the classical phase space which inspires improved classical electron trajectories: these start with…
Carrier-envelope phase controlled isolated attosecond pulses in the nm wavelength range, based on superradiant nonlinear Thomson-backscattering
Szabolcs Hack, Sándor Varró, Attila Czirják
A proposal for a novel source of isolated attosecond XUV -- soft X-ray pulses with a well controlled carrier-envelope phase difference (CEP) is presented in the framework of nonlin…
