Three-dimensional light bullets
Three dimensional light bullets (3D-LB) are the most symmetric solitary waves, being nonlinear wavepackets propagating without diffraction and dispersion. Since their theoretical prediction, the observation...
PublicationsDispersion analysis of non-normal reflection spectra from monoclinic crystals
Results of the first dispersion analyses of polarized reflection spectra from a monoclinic a-c plane taking properly into account non-normal incidence are reported. Spectra were recorded for the incidence...
PublicationsDetermination of the dielectric tensor function of triclinic CuSO4∙5H2O
We present the first successful dispersion analysis of a triclinic crystal in the infrared spectral region.The corresponding scheme involves the parallel evaluation of 12 polarized reflection spectra recordedfrom...
PublicationsFemtoammeter on the base of SQUID with thin-film flux transformer
A SQUID current sensor with integrated input coil is designed and fabricated using our new technology with Nb-AlOx-Nb cross-type Josephson junctions. The white noise level of the SQUID was measured to...
PublicationsThickening of thin laser crystallized silicon films by solid phase epitaxy for photovoltaic applications
Multicrystalline silicon films up to 2 μm thick with grain sizes up to 100 μm were prepared on glass substrates by laser crystallization followed by solid phase epitaxy of electron beam deposited amorphous...
PublicationsOptimum Integration Procedures for Supercontinuum Simulation
We study numerical solutions of the generalized nonlinear Schro¨dinger equation (GNLSE), focusing on the advantage of integrating the nonlinear part of the equation in the frequency domain (FD), rather...
PublicationsRaman spectroscopic detection of Nickel impact on single Streptomyces cells – possible bioindicators for heavy metal contamination
Heavy metal contamination of soil has an immense impact on the surrounding environment, such as the ground water, and hence, has become an important issue within bioremediation. Therefore, heavy metal...
PublicationsRaman and infrared spectroscopic study of synthetic ungemachite, K3Na8Fe(SO4)6(NO3)26H2O
Iron is an important element usually found in atmospheric particulate matter, and its occurrence can be attributed to both natural and anthropogenic sources. It is an accepted fact that the atmospheric...
PublicationsTowards automated segmentation of cells and cell nuclei in nonlinear optical microscopy
Nonlinear optical (NLO) imaging techniques based e.g. on coherent anti-Stokes Raman scattering (CARS) or two photon excited fluorescence (TPEF) show great potential for biomedical imaging. They do not...
PublicationsExperimentally verified inductance extraction and parameter study for superconductive integrated circuit wires crossing ground plane holes
As the complexity of Rapid Single Flux Quantum (RSFQ) circuits increases, both current and energy consumption of the circuits become important design criteria. Various new concepts such as inductive biasing...
