Control of molecular alignment using tailored picosecond laser pulses — •Stefanie Kerbstadt¹, Emil Zak¹, Andrey Yachmenev¹, Sebastian Trippel^1,2, and Jochen Küpper^1,2,3 — ¹Center for Free-Electron Laser Science, Deutsches Elektronen-Synchrotron DESY, Hamburg — ²Center for Ultrafast Imaging, Universität Hamburg — ³Department of Physics, Universität Hamburg

The control of molecular axes is essential for fundamental studies of molecular structure and of chemical reactions. Strong non-resonant laser fields have been established as powerful tool to control and to fix molecular axes in space, providing access to molecular-frame spectroscopy and imaging experiments. Here, we present experimental as well as theoretical results on the refined control of field-free molecular alignment and angular-momentum alignment by employing shaped picosecond pulses to a ground state-selected cold molecular beam of carbonylsulfid (OCS).
