Ultrafast configuration changes and anomalous diffusion of an aromatic adsorbate on rare-gas nanoparticles
Arne Morlok, Philipp Elsässer, Ulrich Bangert +5
Nanoparticles (NPs) exhibit tunable catalytic properties and serve as nanoreactors for controlled multimolecular chemistry. The kinetics and reactivity of such systems are critical…
Size characterization of neutral rare-gas clusters based on time-resolved polarization anisotropy measurements
Arne Morlok, Grzegorz Kowzan, Ulrich Bangert +3
The size determination of neutral clusters is experimentally challenging. In particular, weakly-bound rare-gas clusters tend to fragment upon ionization, resulting in systematic er…
A phase-modulation interferometer for intense, ultrashort, near infrared laser pulses
S. Ganeshamandiram, M. Niebuhr, F. Richter +4
The investigation of coherent phenomena in strong-field processes requires interferometric measurement schemes with high selectivity to disentangle the complex nonlinear response o…
Low-dispersive phase-modulated rapid scanning interferometry
Fabian Richter, Ulrich Bangert, Friedemann Landmesser +3
Time-domain interferometry is an important principle in Fourier transform (FT) and nonlinear femto- to attosecond spectroscopy. To optimize the resolution and sensitivity of this a…
High-resolution rapid-scanning Fourier-transform spectroscopy of ultracold atoms
Friedemann Landmesser, Nicolai Gölz, Ulrich Bangert +2
Femtosecond interferometry combined with acousto-optical phase modulation is an effective approach to implement various types of coherent nonlinear and multidimensional spectroscop…
