SQUID Amplifiers for Axion Search Experiments

In the experiments for dark-matter QCD-axion searches very weak microwave signals from a low-temperature high-Q resonant cavity should be detected with the highest sensitivity. The best commercial low-noise...

Ultrasensitive and towards single molecule SERS: general discussion

Plasmonic enhancement of SERS measured on molecules in carbon nanotubes

We isolated the plasmonic contribution to surface-enhanced Raman scattering (SERS) and found it to be much stronger than expected. Organic dyes encapsulated in single-walled carbon nanotubes are ideal...

Bulk absorption properties of LBO crystals

We present the results of comprehensive bulk absorption studies on numerous LBO crystals at 1070nm, 532nm and 355nm using the sandwich-LID measurement concept. One aim of the studies is answering the question...

Theory of SERS enhancement: general discussion

Molecular Relaxation Processes in Nucleic Acids Components as Probed with Raman Spectroscopy

In this work the Raman total half bandwidths of five free nucleic acids components (cytidine - 5' - monophosphate, 2' - deoxycytidine 5' - monophosphate, 2' - deoxyguanosine - 5' - monophosphate, thymidine...

Aktiver Laserschutz für flexible Materialien durch Solarzellenbeschichtung

- Handlungsbedarf hinsichtlich aktivem Laserschutz für flexible Materialien - Dünnschicht-Solarzellen als großflächige optische Sensoren - Integration von Solarzellen in passive Laserschutzgewebe -...

Analytical SERS: general discussion

Do you get what you see? Understanding molecular self-healing

The self-healing ability of self-healing materials is often analyzed via morphologic microscopy images. Here it was possible to show that morphologic information alone is not sufficient to judge the status...

Saphir-Faser-Bragg-Gitter für die Hochtemperatursensorik

Saphir-Faser-Bragg-Gitter (SFBG) sind neuartige Temperatursensoren, die mittels fs-Laserpulsen in einkristallinen Saphirfasern erzeugt werden, wobei durch Wellenlängenmultiplexen mehrere Gitter in eine...
