Laser Infrastructure for Multi-Dimensional Spectroscopy from XUV to Mid-IR — •Patrick Rupprecht, Lennart Aufleger, Thomas Ding, Marc Rebholz, Carina da Costa Castanheira, Stephan Goerttler, Alexander Magunia, Christian Ott, and Thomas Pfeifer — Max-Planck-Institut für Kernphysik, Heidelberg, Germany

Two-Dimensional Femtosecond Spectroscopy (2DFS) has developed into an indispensable tool to investigate vibrational and electronic couplings in molecular dynamics [Jonas, Annu. Rev. Phys. Chem. 2003]. The presented setup at MPI for Nuclear Physics, Heidelberg, will extend conventional 2DFS schemes towards multi-dimensional, multi-color transient spectroscopy. Based on a 20 mJ pulse energy, 1 kHz repetition-rate Titanium:Sapphire laser system, the optical setup will provide attosecond pulses in the XUV (with maximum photon energies beyond 150 eV), few-cycle pulses in the visible to near infrared spectral region, as well as multi-mJ, femtosecond tunable-wavelength pulses from 1.1 µm to 2.6 µm from an OPA. In combination with the already existing four-quadrant split mirror, this setup targets electron correlation dynamics in atomic and molecular systems. Of particular interest is also the metrology of absorption line shape changes to quantify the influence of strong laser fields from fundamental to complex systems [Ott et al., Science 2013].
