Journal ArticleDOI
Laser-induced alignment and orientation of quantum-state-selected large molecules
Lotte Holmegaard,Jens H. Nielsen,Iftach Nevo,Henrik Stapelfeldt,Frank Filsinger,Jochen Küpper,Gerard Meijer +6 more
TL;DR: An unprecedented degree of laser-induced one-dimensional alignment (cos;(2)theta_(2D)=0.97) and strong orientation of state-selected iodobenzene molecules are demonstrated, enabling experiments on pure samples of polar molecules in their rotational ground state.
Journal ArticleDOI
X-ray diffraction from isolated and strongly aligned gas-phase molecules with a free-electron laser
Jochen Küpper,Stephan Stern,Lotte Holmegaard,Frank Filsinger,Arnaud Rouzée,Artem Rudenko,Artem Rudenko,Per Johnsson,Andrew V. Martin,M.

Wunderer,Gerard Meijer,Joachim Ullrich,Henrik Stapelfeldt,Daniel Rolles,Henry N. Chapman +55 more
TL;DR: In this paper, the authors reported experimental results on x-ray diffraction of quantum-state-selected and strongly aligned ensembles of the prototypical asymmetric rotor molecule 2,5-diiodobenzonitrile using the Linac Coherent Light Source.
Journal ArticleDOI
Quantum-state selection, alignment, and orientation of large molecules using static electric and laser fields
Frank Filsinger,Jochen Küpper,Gerard Meijer,Lotte Holmegaard,Jens H. Nielsen,Iftach Nevo,Jonas L. Hansen,Henrik Stapelfeldt +7 more
TL;DR: Unprecedented degrees of laser-induced alignment and orientation of iodobenzene molecules are demonstrated when the state-selected samples are used and provide unique possibilities for many novel experiments in chemistry and physics.
Journal ArticleDOI
Femtosecond and nanometre visualization of structural dynamics in superheated nanoparticles

TL;DR: In this article, single Xe clusters are superheated using an intense optical laser pulse and the structural evolution is imaged with a single X-ray pulse, and the surface softening on the nanometre scale is resolved within 100 fs at the vacuum/sample interface.
Journal ArticleDOI
Laser-induced 3D alignment and orientation of quantum state-selected molecules
Iftach Nevo,Lotte Holmegaard,Jens H. Nielsen,Jonas L. Hansen,Henrik Stapelfeldt,Frank Filsinger,Gerard Meijer,Jochen Küpper +7 more
TL;DR: It is shown that the degree of 3-dimensional alignment and orientation is strongly enhanced when rotational state-selected molecules, rather than molecules in the original molecular beam, are used as targets.
