Picosecond pulse-shaping for strong three-dimensional field-free alignment of generic asymmetric-top molecules
Terry Mullins, Evangelos Thomas Karamatskos, Joss Wiese +5
Fixing molecules in space is a crucial step for the imaging of molecular structure and dynamics. Here, we demonstrate three-dimensional (3D) field-free alignment of the prototypica…
X-ray diffractive imaging of controlled gas-phase molecules: Toward imaging of dynamics in the molecular frame
Thomas Kierspel, Andrew Morgan, Joss Wiese +25
We report experimental results on the diffractive imaging of three-dimensionally aligned 2,5-diiodothiophene molecules. The molecules were aligned by chirped near-infrared laser pu…
Knife edge skimming for improved separation of molecular species by the deflector
Sebastian Trippel, Melby Johny, Thomas Kierspel +7
A knife edge for shaping a molecular beam is described to improve the spatial separation of the species in a molecular beam by the electrostatic deflector. The spatial separation o…
Strongly aligned gas-phase molecules at Free-Electron Lasers
Thomas Kierspel, Joss Wiese, Terry Mullins +27
We demonstrate a novel experimental implementation to strongly align molecules at full repetition rates of free-electron lasers. We utilized the available in-house laser system at…
Formation and relaxation of RbHe exciplexes on He nanodroplets studied by femtosecond pump and picosecond probe spectroscopy
C. Giese, T. Mullins, B. Gruener +3
Vibrationally resolved photoionization spectra of RbHe exciplexes forming on He nanodroplets are recorded using femtosecond pump-probe spectroscopy with amplitude-shaped probe puls…
Spatial separation of state- and size-selected neutral clusters
Sebastian Trippel, Yuan-Pin Chang, Stephan Stern +3
We demonstrate the spatial separation of the prototypical indole(H2O) clusters from the various species present in the supersonic expansion of mixtures of indole and water. The maj…
