Coherence of XUV Laser Sources
This article reviews recent developments in research on coherence properties of femtosecond XUV and x-ray lasers. Coherence is one of the most conspicuous features of laser sources. It describes how an electromagnetic wave field is correlated at different times and at different points in space. Coherence is a property that enables stationary interferences and thereby enables holographic and dif...
متن کاملResonant Laser Excitation of Molecular Wires
We investigate the influence of external laser excitations on the average current through bridged molecules. For the computation of the current, we use a numerically very efficient formalism that is based on the Floquet solutions of the time-dependent molecule Hamiltonian. It is found that the current as a function of the laser frequency exhibits characteristic peaks originating from resonant e...
متن کاملMolecular dynamics of liquid benzene via femtosecond pulses laser excitation
2014 We analyse the complex response of liquid benzene to the applied 45 fs FHWM optical pulses by using a polarization sensitive transient grating technique. An electronic contribution to the nonlinear polarization is distinguished from three other processes which, we demonstrate, originate in polarizability modifications associated to molecular motions. Additionally, we present evidence that ...
متن کاملSingle-order laser high harmonics in XUV for ultrafast photoelectron spectroscopy of molecular wavepacket dynamics
We present applications of extreme ultraviolet (XUV) single-order laser harmonics to gas-phase ultrafast photoelectron spectroscopy. Ultrashort XUV pulses at 80 nm are obtained as the 5th order harmonics of the fundamental laser at 400 nm by using Xe or Kr as the nonlinear medium and separated from other harmonic orders by using an indium foil. The single-order laser harmonics is applied for re...
متن کاملXUV Transient Absorption Spectroscopy: Probing Laser-Perturbed Dipole Polarization in Single Atom, Macroscopic, and Molecular Regimes
We employ an extreme ultraviolet (XUV) pulse to impulsively excite dipole polarization in atoms or molecules, which corresponds to coherently prepared superposition of excited states. A delayed near infrared (NIR) pulse then perturbs the fast evolving polarization, and the resultant absorbance change is monitored in dilute helium, dense helium, and sulfur hexafluoride (SF6) molecules. We observ...
