Ernstorfer, R.; Gundlach, L.; Zimmermann, C.; Willig, F.; Eichberger, R.; Riedle, Eberhard ORCID: 0000-0002-2672-5718 (2004): Generation of sub-20 fs Tunable Visible Pulses from a 100 kHz NOPA For Measuring Ultrafast Heterogeneous Electron Transfer. Ultrafast Optics IV, June, 2003, Vienna, Austria.
Full text not available from 'Open Access LMU'.


We describe the design and performance of a noncollinear optical parametric amplifier that can be pumped by the output of a commercial 100 kHz Ti:sapphire regenerative amplifier. The output of the NOPA is compressed to sub-20 fs length and tunable from 460 nm to beyond 1 mum. The maximum pulse energy is 750 nJ. The system is used to measure photoinduced electron transfer in a perylene/TiO(2) system with unprecedented temporal resolution.
