Diode pumped solid state kilohertz disk laser system for time-resolved combustion diagnostics under microgravity at the drop tower Bremen
We describe a specially designed diode pumped solid state laser system based on the disk laser architecture for combustion diagnostics under microgravity (µg) conditions at the drop tower in Bremen. The...
PublicationsExpanding Multimodal Microscopy by High Spectral Resolution Coherent Anti-Stokes Raman Scattering Imaging for Clinical Disease Diagnostics
Over the past years fast label-free nonlinear imaging modalities providing molecular contrast of endogenous disease markers with subcellular spatial resolution have been emerged. However, applications...
PublicationsStructural properties of Gold modified YBa2Cu3O7-δ thin films
YBa2Cu3O7-d thin films were prepared by pulsed laser deposition whereby single-crystalline Au nanoparticles were embedded via a self-assembly process out of an initial Au seed layer. The size of the Au...
PublicationsCharacterization of 700 μJ T rays generated during high-power laser solid interaction
Laser produced solid density plasmas are well known as table top sources of electromagnetic radiation. Recent studies have shown that energetic broadband THz pulses can also be generated from laser driven...
PublicationsNonlinear Dependences of Optical Properties of Spherical Core–Shell Silver–Gold and Gold–Silver Nanoparticles on Their Parameters
Modeling of nonlinear optical properties of spherical core-shell gold-silver and silver-gold nanoparticles (NPs) placed in water was carried out on the base of extended Mie theory. Efficiency cross sections...
PublicationsMorphology of Si/SiO2/Ni nanostructures with swift heavy ion tracks in silicon oxide
Abstract—Si/SiO2/Ni nanostructures are fabricated by the irradiation of an oxidized Si surface with swift heavy ions, nanopore etching in the SiO2 layer, and the electrochemical deposition of nickel...
PublicationsPositive magnetoresistive effect in Si/SiO2(Cu/Ni) nanostructures
A structure consisting of a nanoporous dielectric film (SiO2) containing alternated layers of metal (Cu/Ni) in the pores on a semiconductor substrate (n-Si) has been formed using the swift heavy ion track...
PublicationsCorrelations in Ultrafast Optical Kerr Gating between Pump Intensity, Efficiency, and Time Resolution
Optical-Kerr-Gating (OKG) by high refractive index materials (telluride and SF56 glasses, ZnS) in dual-frequency fs-laser pump-probe ex-periments reveals correlations between pump beam intensity (800 nm),...
PublicationsMagnetization dynamics of magnetic domain wall imprinted magnetic films
The influence of micromagnetic objects on the dynamic magnetic excitation in magnetic thin films is studied by imprinting periodic domain wall patterns through selective ion irradiation in exchange biased...
PublicationsRaman Spectroscopy-An Innovative and Versatile Tool To Follow the Respirational Activity and Carbonate Biomineralization of Important Cave Bacteria
Raman gas spectrometry is introduced as a unique tool for the investigation of the respiratory activity that is indicative for growth of bacteria involved in biomineralization. Growth of these bacteria...
