Dc SQUID based on a three-band superconductor with broken time-reversal symmetry

The behavior of a dc superconducting quantum interference device (SQUID), based on dirty-point contacts between a single-band and three-band superconductor with broken time-reversal symmetry, is investigated....

A Microwave Splitter for Superconducting Quantum Circuits

Applications of up-to-date cryoelectronics, especially in quantum microwave engineering, require instruments that operating identically to an optical beam splitter. Using niobium technology for the application...

Raman spectral imaging of cells and monitoring of intracellular uptake nanoparticles

Bioimaging of Silicon nanoparticles for cancer diagnosis by mean of Raman micro-spectroscopy

Ignition delay times of single kerosene droplets based on formaldehyde LIF detection

Single droplet ignition experiments were performed with GTL kerosene, Jet A-1 and Exxsol D80 (reduced aromatics) in the temperature range from 550 to 900 K in air at 3 bar. The laser-induced fluorescence...

Sensitive und absolute Absorptionsmessung mittels laserinduzierter Teststrahlablenkung (LID)

Hohe Sensitivität gepaart mit einfacher absoluter Kalibrierung, das am IPHT Jena entwickelte LID-Absorptionsmessverfahren vereint beides. Das neue „LID-Sandwich-Konzept“ erlaubt darüber hinaus die...

Bessel beam coherent anti-Stokes Raman scattering microscopy

We report about laser scanning coherent anti-Stokes Raman scattering (CARS) microscopy using a Bessel beam to enhance the lateral resolution. This study covers a numerical investigation that predicts an...

Dye-sensitized PS-b-P2VP-templated nickel oxide films for photoelectrochemical applications

Moving from homogeneous water-splitting photocatalytic systems to photoelectrochemical devices requires the preparation and evaluation of novel p-type transparent conductive photoelectrode substrates....

SiO2-Al2O3-La2O3 Glass – a Superior Medium for Optical Kerr Gating at Moderate Pump Intensity

Novel SiO2-Al2O3-La2O3 glass shows a switching efficiency   70 % in  = 140 fs for dual wavelengths optical Kerr gating at 1 TW/cm2 and is compared to other Kerr materials with larger n2.

Temporal walk-off affecting optical Kerr gating in the sub-ps time range

During the past decades, optical Kerr gating (OKG) evolved to one of the most important optical switching techniques for broadband analysis of ultrafast optical processes [1]. For maximum OKG efficiency...
