Formation of supersaturated Au–Ni nanoparticles via dewetting of an Au/Ni bilayer
Supersaturated Au–Ni solid-solution nanoparticles are formed via dewetting of a nanometer Au/Ni thin bilayer using rapid thermal treatment. Annealing at temperatures well below the melting temperatures...
PublicationsOxide-free hybrid silicon nanowires: From fundamentals to applied nanotechnology
The ability to control physical properties of silicon nanowires (Si NWs) by designing their surface bonds is important for their applicability in devices in the areas of nano- lectronics, nano-photonics,...
PublicationsEvolution of lasing during FBG-inscription in a Yb-Al-doped laser fiber
We report on the inscription of a fiber Bragg grating in a Yb-Al-doped fiber under pumping conditions and on the spectral properties of a laser operating with such a grating.
PublicationsUV-induced photodarkening and photobleaching in UV-femtosecond-pulse-written fibre Bragg gratings
Photodarkening and photobleaching effects in case of UV-femtosecond-pulse exposure of optical fibres are investigated. We evaluate the existence of loss equilibrium states in Yb-doped and Yb-free fibres....
Publications100 kW peak power picosecond thulium-doped fiber amplifier system seeded by a gain-switched diode laser at 2 µm
We report on the generation of picosecond pulses at 2 μm directly from a gain-switched discrete-mode diode laser and their amplification in a multistage thulium-doped fiber amplifier chain. The system...
PublicationsMagnetic nanoparticle heating and heat transfer on a microscale: Basic principles, realities and physical limitations of hyperthermia for tumour therapy
In this review article, we present basic principles of magnetically induced heat generation of magnetic nanoparticles for application in magnetic particle hyperthermia. After explanation of heating mechanisms,...
PublicationsMechanism of protonation induced changes in Raman spectra of a trisheteroleptic ruthenium complex revealed by DFT calculations
A systematic DFT/(resonance) Raman spectroscopic study of the protonation/deprotonation induced changes in the vibrational spectra of a trisheteroleptic ruthenium complex [(tbbpy)Ru(II)(tmbibzimH2)(dppz)]2+...
PublicationsIdentification of meat-associated pathogens via Raman microspectroscopy
The development of fast and reliable sensing techniques to detect food-borne microorganisms is a permanent concern in food industry and health care. For this reason, Raman microspectroscopy was applied...
PublicationsMicro-Structured Fiber Interferometer as Sensitive Temperature Sensor
We report on a fast and sensitive temperature sensor using a micro-structured or photonic crystal fiber interferometer with a high germanium doped fiber core. The wavelength sensitivity for temperature...
PublicationsFiber Bragg grating inscription in few-mode highly birefringent microstructured fiber
In this paper we present the technology of fiber Bragg grating (FBG) inscription in novel highly birefringent (HB) few-mode microstructured fibers (MSF) with two different – nanosecond and femtosecond...
