Fast wavelength-switching of a diode-pumped solid-state disk laser

The functionality of two experimental setups for fast wavelength-switching of an Yb:YAG disk laser is tested and characterized. The first setup consists of two resonators sharing one disk. Both resonators...

Microstructure and lattice bending in polycrystalline laser-crystallized silicon thin films for photovoltaic applications

Grain size, grain boundary population, orientation distribution and lattice defects of polycrystalline silicon thin films are investigated by electron backscatter diffraction (EBSD). The silicon thin films...

A new approach towards the detection and identification of circulating tumour cells

Voltage-current and voltage-flux characteristics of asymmetric high T-C DC SQUIDS

We report measurements of transfer functions and flux shifts of 20 on-chip high TC DC SQUIDs half of which were made purposely geometrically asymmetric. All of these SQUIDs were fabricated using standard...

Superconductor-to-Semiconductor Interface Circuit for High Data Rates

We present a new kind of rapid-single-flux-quantum (RSFQ) output driver together with a pseudomorphic high electron mobility transistor (p-HEMT) amplifier both operating at liquid helium temperature. The...

High-energy soliton pulse generation with a passively mode-locked Er/Yb-doped multifilament-core fiber laser

We report the generation of high-energy short pulses from a mode-locked erbium/ytterbium-doped largemode-area multifilament-core fiber laser operating in the purely anomalous dispersion regime. The self-starting...

A disposable and cost efficient microfluidic device for the rapid chip-based electrical detection of DNA

Requirements for a point-of-care device are an easy and robust read-out and – above all – a simple handling. We integrated an established robust electrical read-out for DNA-chips into a microfluidic...

Nanostructural Superconducting Materials for Fault Current Limiters and Cryogenic Electrical Machines

Materials of the Y–Ba–Cu–O (melt-textured YBa2Cu3O7¡±-based materials or MT-YBCO) and Mg–B–O (MgB2-based materials) systems with high superconducting performance, which can be attained due...

Transversal Load Sensing With Fiber Bragg Gratings in Microstructured Optical Fibers

We present fiber Bragg grating based transversal load sensing with a highly birefringent microstructured optical fiber. For the bare fiber, the change of the Bragg peak separation under a transverse line...

Recent advances in single-molecule sequencing

Recent advances in sequencing technologies exhibit a tendency towards single-molecule sequencing, which eventually will lead to the commercial implementation of such platforms. For this purpose dye labelling...
