“…The last step, photorecombination, is now well understood in terms of quantum scattering calculations developed in the context of photoionization. [15,16,19] Most remarkably, the strong laser field does not lead to a measurable distortion of the electronic wave functions within the accuracy of current experiments, even in polarizable systems like xenon [20] or in molecules with appreciable extension along the direction of the laser field like CO 2 . [4,5] The second step, propagation of the electron wavepacket, is largely dominated by the laser field and is well described by classical equations as evidenced by, e.g.…”

“…Since the returning electron wave diffracts in the electrostatic molecular potential before it recombines, the high-harmonic spectrum reveals structural signatures such as twocenter interference [12] and features of electronic structure. [13][14][15][16] In addition, a high-harmonic spectrum also encodes dynamical information. Under precisely controlled experimental conditions, each photon energy in the spectrum is emitted by a unique electron trajectory, i.e.…”

“…Following the reasoning behind the three-step model [48] and the factorization of the high-harmonic-generation (HHG) process [49][50][51], we treat the HHG process as a chronological sequence of ionization, propagation, and recombination steps. We first study the ionization yields from the three p orbitals.…”

“…While HHG spectroscopy can measure distinct features in the photorecombination of an electron to the outer p-subshells of rare gas atoms, such as the Cooper minimum in Ar [11,12] and the giant dipole resonance in Xe [2], HHG measurements for linear polarization are fundamentally limited. Specifically, they can only give access to the energy dependence of the differential PRCS σ (E, α) (where α is the angle between the photon polarization axis and the recombining electron's momentum).…”

“…It can be shown that the dipole moments d 0,0 and d 1,−1 given by equation (12) for F 2 = 0 coincide with those in [24] for a monochromatic field, while d 1,+1 = 0. Since each of the three factors in the parametrization (12) has a clear physical meaning in terms of the three-step HHG scenario [25,26] and since the propagation factor χ (l,q) is insensitive to the atomic dynamics, one can extend the parametrization (12) to the case of a neutral atom by replacing the tunnelling rate st (F ) and the matrix elements D ll [or σ (E, α)] by their counterparts for a given atom, as is done in [16].…”
