STROBE Seminar: Dr. Eberhard Riedle, ‘Ultrashort pulses tunable from the DUV to the MIR for molecular dynamics’

I will review our recent efforts to generate tunable optical pulses over the widest spectral range. The central part of our approach are visible noncollinear parametric amplifiers. These can then be frequency doubled or mixed with the pump radiation down to as far as 190 nm with sub-30 fs pulse length. By difference frequency generation or even parametric amplification we can we can reach the NIR and MIR range. The IR pulses are CEP stable and nearly single cycle.Combined with white light detection these tunable pulses are ideal sources to investigate the dynamics of increasingly complex photophysical and chemical systems. As an example I will show the complete characterization – all time involved constants and efficiencies – of a lht driven unidirectional molecular motor.
