Double ionization of H2 by intense attosecond laser pulses
We present calculations of the double ionization of H2 induced by an intense attosecond laser pulse at a photon energy of 40 eV using the time-dependent close-coupling method within the fixed nuclei approximation. We focus on two-photon absorption processes and examine how the response of the ejected electrons, in particular the singleand the double-energy differential probabilities, is affecte...
متن کاملRecollisions, bremsstrahlung, and attosecond pulses from intense laser fields.
Over the last two decades the interaction of atoms with intense laser light has been a rich area of research with many interesting and important discoveries. One of these major findings has been high-harmonic generation ~HHG!; in this process the strongly driven atomic system reradiates energy at odd multiples ~owing to the symmetry of the process! of the driving frequency. Using HHG it has bee...
متن کاملAttosecond pulses measured from the attosecond lighthouse
The attosecond lighthouse is a method of using ultrafast wavefront rotation with high-harmonic generation to create a series of coherent, spatially separated attosecond pulses. Previously, temporal measurements by photoelectron streaking characterized isolated attosecond pulses created by manipulating the single-atom response1–4. The attosecond lighthouse, in contrast, generates a series of pul...
متن کاملSignatures of attosecond electron tunneling dynamics in the evolution of intense few-cycle light pulses
The sensitivity of electron tunneling to the phase of an ionizing light field is shown to manifest itself in detectable features in the spectral and temporal evolution of intense few-cycle light pulses in an ionizing medium. An ultrafast buildup of electron density in the regime of tunneling ionization gives rise to a modulation of a few-cycle field wave form and enhances the short-wavelength p...
متن کاملIntense single attosecond pulses from surface harmonics using the polarization gating technique
Harmonics generated at solid surfaces interacting with relativistically strong laser pulses are a promising route towards intense attosecond pulses. In order to obtain single attosecond pulses one can use few-cycle laser pulses with carrier-envelope phase stabilization. However, it appears feasible to use longer pulses using polarization gating—the technique known for a long time from gas harmo...
