    HIGH-ORDER HARMONIC-GENERATION CUTOFF

    , PHYSICAL REVIEW A, Vol: 48, Pages: R3433-R3436, ISSN: 1050-2947

    We have experimentally determined the harmonic-generation cutoff as a function of the laser intensity in neon using an intense, short-pulse Ti:sapphire laser. The experimental cutoff is lower than that obtained in single-atom calculations. Using a simple quantum-mechanical approach to harmonic generation valid at high intensity, we show that the difference is due to the effect of propagation.

    Trapping of Population at Rydberg States during Strong-Field Multiphoton Ionization

    , LASER PHYSICS, Vol: 3, Pages: 640-643, ISSN: 1054-660X

    A new mechanism of atomic stabilization in the process of resonance ionization via Rydberg states is discussed. It is shown that strong resonance interaction of Rydberg states with a low lying state substantially suppresses ionization from this state and leads to the trapping of population at Rydberg states. Raman-type coupling of Rydberg states via continuum is shown to be essential for the effect even when bound-free interaction is weak.

    Coherent Control and Collapse of Symmetry in a Two-Level System in an Intense Laser Field

    , LASER PHYSICS, Vol: 3, Pages: 375-380, ISSN: 1054-660X

    We present the analytical solution for a two-level system dressed by an intense laser field and discuss new phenomena arising under these conditions. We show that intense ultrashort laser pulses always break the symmetry of the two-level system, resulting in the generation of even-order harmonics of the incident light. Both the phase of the laser-induced polarization of the system and the emission spectrum can be controlled using experimentally accessible parameters. The control is sufficient to allow us to suppress odd and enhance even harmonics. We propose that phase control of nonlinear polarization can be used for quasi-phase matching of high-harmonic radiation.

    Spontaneous Bremsstrahlung of an Electron in an Intense Laser Field: Classical vs. Quantum Approach

    , LASER PHYSICS, Vol: 3, Pages: 365-372, ISSN: 1054-660X

    We consider the scattering of a classical electron in the presence of an intense laser field and the spectrum of the arising spontaneous emission. Our results are compared with analogous quantum-mechanical calculations. Although the quantum expressions contain the Planck constant only in the Coulomb logarithm, i.e., have a very weak dependence on (h) over bar, and although in a weak field quantum and classical mechanics yield the same result (except for the slightly different Coulomb logarithm), in the presence of a strong field the difference between classical and quantum results becomes significant. In our opinion, this difference is due to the difference in behavior of a completely localized classical and completely delocalized quantum electron scattered by the ion in the presence of the strong field.

    GENERATION OF HIGH-ORDER HARMONICS FROM INERTIALLY CONFINED MOLECULAR-IONS

    , PHYSICAL REVIEW A, Vol: 48, Pages: 580-590, ISSN: 1050-2947

    We consider the generation of high-order harmonics from inertially confined diatomic molecular ions driven by strong short pulses of laser radiation. Using a simple analytically solvable model, we show that diatomic molecular ions can be a very efficient source of high-order harmonics. The sources of the strong nonlinear response are charge-resonant states of odd-charge molecular ions. We also discuss possibilities for quasi-phase-matching, which are given by the molecular ions and which have no analogies in atomic systems.
