We have developed an analytical theory explaining how the single-atom efficiency of high-harmonic generation scales with laser frequency, and verified this by numerically solving the time-dependent Schrödinger equation in three spatial dimensions. A

By solving the time-dependent Schrodinger equation numerically, we simulate high-order harmonic generation from one-dimensional hydrogen molecules driven by intense laser pulses of different wavelengths. The electron-electron interaction and the vibr

A new technique for probing the structural rearrangements of molecules following ionization has recently been demonstrated. Whilst straightforward to implement, this technique offers remarkable time resolution, allowing intramolecular nuclear dynamic

We analyse three different formulations of the strong-field approximation for high-harmonic generation in diatomic molecules, based on length, velocity and acceleration form for the recombination amplitude. We compare the predictions for the two-cent

The effect of vibrational motion on harmonic generation in molecules is studied within the strong-field approximation. Simple expressions are given for the cut-off energy and for the ratio of spectral intensities from two isotopes. The latter is base

The generation of high-order harmonics in small diatomic molecules is theoretically investigated with inclusion of the vibrational degree of freedom. The results obtained from the solution of the time-dependent Schrodinger equation for a model H2 mol

At high laser intensities, three step recollision processes such as high order harmonic generation and high-order ATI, are normally severely suppressed due to the magnetic field component of the laser pulse. However, if the laser pulse and relativist

By applying time-dependent density functional theory to a two-dimensional multielectron atom subject to strong circularly polarized light pulses, we confirm that the ionization of p orbitals with defined angular momentum depends on the sense of rotat

We analyze the orientation dependence of harmonic amplitudes and phases from laser driven H2+. We use the Lewenstein model, with and without employing the saddle-point approximation for the summation over electron momenta. This means that the directi
