“…At the same time, the peaks were found to be compatible with the "antenna" (Kuchiev 1987) or the "recollision" mechanism (Corkum 1993) as was first shown within classical considerations Moshammer et al 2000;Weber et al 2000). Subsequently, a variety of theoretical predictions (see the detailed discussion and references in Dörner et al (2002)) based on S-matrix theory, on the numerical solution of the time dependent Schrödinger equation (TDSE) as well as on the classical or semi-classical approximations essentially established the double peakstructure and recollision as the dominant NS double ionisation mechanism (see also earlier measurements with circularly polarized light by Fittinghoff et al (1994) and Dietrich et al (1994)). In the sequential regime a broader distribution is observed with a single peak at zero momentum along the field axis (see (3) in Figure 17).…”

Recoil-ion and electron momentum spectroscopy is a rapidly developing technique that allows one to measure the vector momenta of several ions and electrons resulting from atomic or molecular fragmentation. In a unique combination, large solid angles close to π Microccopes -the "bubble chambers of atomic physics" -mark the decisive step forward to investigate many-particle quantum-dynamics occurring when atomic and molecular systems or even surfaces and solids are exposed to time-dependent external electromagnetic fields.The present review concentrates on just these latest technical developments and on at least four new classes of fragmentation experiments that have emerged within about the last five years. First, multi-dimensional images in momentum space brought unprecedented information on the dynamics of single-photon induced fragmentation of fixed-in-space molecules and on their structure. Second, a break-through in the investigation of highintensity short-pulse laser induced fragmentation of atoms and molecules has been achieved by using Reaction Microccopes. Third, for electron and ion-impact, the investigation of twoelectron reactions has matured to a state such that first fully differential cross sections (FDCS) are reported. Forth, comprehensive sets of FDCS for single ionisation of atoms by ion-impact, the most basic atomic fragmentation reaction, brought new insight, a couple of surprises and unexpected challenges to theory at keV to GeV collision energies. In addition, a brief summary on the kinematics is provided at the beginning. Finally, the rich future potential of the method is shortly envisaged.2

“…As the high-harmonic beam polarization follows the atomic dipole direction, which is directly related to the driving laser polarization, one should expect to control the harmonic ellipticity by the driving laser ellipticity [3][4][5] . However, the recombination probability and consequently the harmonic generation efficiency drops dramatically with this latter 6,7 . Several methods were proposed to overcome this restriction [8][9][10][11][12][13][14][15][16] , but only three of them really show the production of high harmonics with elliptical polarization and non-negligible efficiency.…”

Towards enabling femtosecond helicity-dependent spectroscopy with high-harmonic sources

et al. 2015

Recent advances in high-harmonic generation gave rise to soft X-ray pulses with higher intensity, shorter duration and higher photon energy. One of the remaining shortages of this source is its restriction to linear polarization, since the yield of generation of elliptically polarized high harmonics has been low so far. We here show how this limitation is overcome by using a cross-polarized two-colour laser field. With this simple technique, we reach high degrees of ellipticity (up to 75%) with efficiencies similar to classically generated linearly polarized harmonics. To demonstrate these features and to prove the capacity of our source for applications, we measure the X-ray magnetic circular dichroism (XMCD) effect of nickel at the M 2,3 absorption edge around 67 eV. There results open up the way towards femtosecond time-resolved experiments using high harmonics exploiting the powerful element-sensitive XMCD effect and resolving the ultrafast magnetization dynamics of individual components in complex materials.
