Angstrom and attosecond control of free electron wave packets is one of the pinnacles of attosecond science. Orthogonally polarized two-color (OTC) laser fields allow to control the motion of field-ionizing electronic wave packets both in time and space[1]. In OTC pulses time and space are connected and thus an attosecond time scale is established in the polarization plane for both the emitted and...
Molecular ionization by femtosecond light pulses is fascinating phenomena in terms of both the underlying physics and practical implications to selective control of isomerization and fragmentation pathway(s) through the shape of the optical waveform. Triggered by optical field ionization, the outcome of the complex electronic and subsequent nuclear dynamics leading to fragmentation is to a large extent...
Recently, selective fragmentation of polyatomic molecules using the carrier-envelope phase (CEP) of few-cycle ionizing laser pulses as the control parameter [1] has been demonstrated [2]. It was shown that the underlying mechanism is selective removal of specific (inner-valence shell) electrons, which puts the molecule into a dedicated dissociative electronic state from which the molecule then fragments...
Laser induced Coulomb explosion of 1,3-Butadiene is investigated by the COLTRIMS technique. The main fragmentation channels are identified and their momentum distributions are characterized. Remarkably high proton energies are measured and their origin is investigated.
Laser-induced fragmentation of a highly polarisable polyatomic hydrocarbon molecule, 1,3-butadiene is investigated. Cold target recoil-ion momentum spectroscopy is used to record the three-dimensional momentum distributions of the fragments. Fragmentation is accompanied by fast hydrogen migration and chemical bonds are governed by intramolecular dynamics of electrons.
We analyze the dependence of the polarization of THz radiation generated by four-wave-mixing in laser induced plasma filaments on the input polarizations and compare these results to current models for plasma assisted THz generation.
We demonstrate an interferometrically stable pulse multiplexing-amplification-recombination scheme for direct laser amplification of picosecond pulses. Switching from singlepulse amplification to the burst mode increases extraction efficiency, gain in cw-pumped crystals and output energies.

We report the latest progress on the development of a 1-kHz OPCPA system, generating carrier-envelope-phase-stabilized 350-muJ 20-fs pulses at 2.1 mum with suppressed supertluorescence. A proof-of-principle high-harmonic generation experiment in argon was conducted.
