Autor: Schneider C., Rewitz C., Razinskas G., Pfeiffer W., Melchior P., Kramer C., Huang J.-S., Keitzl T., Hecht B., Goetz S., Geisler P., Fischer A., Aeschlimann M., Brixner T., Strüber C., Tuchscherer P., Voronine D. V.

Publikováno v: EPJ Web of Conferences, Vol 41, p 09017 (2013)

Three spectroscopic techniques are presented that provide simultaneous spatial and temporal resolution: modified confocal microscopy with heterodyne detection, space-time-resolved spectroscopy using coherent control concepts, and coherent two-dimensi

Femtosecond Mid-Infrared Study of the Aqueous Solution Photochemistry of a CO-Releasing Molecule (CORM)

Autor: Schatzschneider U., Brixner T., Niesel J., Gehrig D., Kanal F., Rudolf P., Nuernberger P.

Publikováno v: EPJ Web of Conferences, Vol 41, p 05004 (2013)

Ultraviolet irradiation of CO-releasing molecules (CORMs) in water eventually leads to the loss of several carbon monoxide ligands.We show for an exemplary manganese tricarbonyl CORM that only one ligand is photolyzed off on an ultrafast timescale an

Precise and Rapid Detection of Optical Activity for Accumulative Femtosecond Spectroscopy

Autor: Nuernberger P., Buback J., Steinbacher A., Brixner T.

Publikováno v: EPJ Web of Conferences, Vol 41, p 12011 (2013)

We present a fast and sensitive polarimeter combining common-path optical heterodyne interferometry and accumulative spectroscopy to detect rotatory power. The sensitivity of rotatory detection is determined to be 0.10 milli-degrees for a measurement

Exploring Higher-Lying Electronic States of a Molecular Switch by Coherent Triggered-Exchange 2D Electronic Spectroscopy

Autor: Nuernberger P., Buback J., Kullmann M., Ruetzel S., Brixner T.

Publikováno v: EPJ Web of Conferences, Vol 41, p 05001 (2013)

We use pump-repump-probe transient absorption spectroscopy to investigate the role of higher-lying electronic states in the photochemistry of a molecular switch. Moreover, replacing the pump pulse by a pulse-shaper-generated phase-stable double pulse

Deterministic spatio-temporal control of nano-optical fields in optical antennas and nano transmission lines

Autor: Huang, J. S., Voronine, D. V., Tuchscherer, P., Brixner, T., Hecht, B.

Publikováno v: Physical Review B 79, 195441 (2009)

We show that pulse shaping techniques can be applied to tailor the ultrafast temporal response of the strongly confined and enhanced optical near fields in the feed gap of resonant optical antennas (ROAs). Using finite-difference time-domain (FDTD) s
