A full optically operated magnetometer array: an experimental study
We show the operation of an optically pumped magnetometer (OPM) array in a 50 microT magnetic field. The various components for a fully optical and non magnetic detector unit were constructed and evaluated,...
PublicationsSingle-drop optimization of protein crystallization
A completely new crystal-growth device has been developed that permits charting a course across the phase diagram to produce crystalline samples optimized for diffraction experiments. The utility of the...
PublicationsDevelopment of Passive Submillimeter-wave Video Imaging Systems for Security Applications
Passive submillimeter-wave imaging is a concept that has been in the focus of interest as a promising technology for security applications for a number of years. It utilizes the unique optical properties...
PublicationsGrain structure of thin-film silicon by zone melting recrystallization on SiC base layer
The grain structure of thin-film silicon layers obtained by chemical vapor deposition and zone melting recrystallization(ZMR) on SiC barrier layers, as developed for thin film solar cells, have been investigated...
PublicationsInvestigation of laser irradiated areas with electron backscatter diffraction
In this work, two silicon nitride (SiNx) layers with two different refraction indices, deposited on polished or damageetched silicon wafers were locally irradiated by laser pulses. The focus was set on...
PublicationsSample size planning for classification models
In biospectroscopy, suitably annotated and statistically independent samples (e. g. patients, batches, etc.) for classifier training and testing are scarce and costly. Learning curves show the model performance...
PublicationsResults of Measuring the Influence of Casimir Energy on Superconducting Phase Transitions
The ALADIN experiment aims at observing how the critical magnetic field of a superconducting aluminum film is modified, when it constitutes one of the reflecting surfaces of a Casimir cavity. If successful,...
PublicationsThe effect of high-pressure synthesis on flux pinning in MgB2-based superconductors
Increasing the pressure during manufacturing MgB2 enhances the volume pinning force and moves the position of the maximum to higher magnetic fields. A similar shift was observed when Ti or SiC was added...
PublicationsBroadband, diode pumped Yb:SiO2 multicomponent glass laser
Fabrication, spectroscopic properties and laser performance of a Yb:SiO2 multicomponent glass have been investigated in this paper. The glass system comprising of SiO2, Al2O3 and La2O3 excels in terms...
PublicationsNanoscopic Tip Sensors Fabricated by Gas Phase Etching of Optical Glass Fibers
Silica-based fiber tips are used in a variety of spectroscopic, micro- or nano-scopic optical sensor applications and photonic micro-devices. The miniaturization of optical sensor systems and the technical...
