The 390 cm-1 feature of polycrystalline hematite—An optical crystallite size effect

The 390 cm-1 spectral feature of polycrystalline hematite is shown to be caused by a crystallite size effect which is caused by the anisotropic nature of single crystalline hematite. This effect occurs...

Powder sintering process for the manufacturing of novel, highly efficient laser fibers

The reactive powder sintering process for silica glass is a new method to produce rare earth doped fused silica with very high purities. We show how to manufacture the material and explain its main properties...

Double resonance response in nonlinear magnetic vortex dynamics

We present experimental evidences for the dynamical bifurcation behavior of ac-driven magnetic vortex core gyration in a ferromagnetic disk. The dynamical bifurcation, i.e. appearance and disappearance...

CW-diode laser crystallization of sputtered amorphous silicon on glass, SiNx, and SiO2 intermediate layers

The crystallization of amorphous silicon layers deposited by sputtering or electron beam evaporation onto different substrates by diode laser crystallization via the melt is investigated. First we present...

Multiplexing of six micro-displacement suspended-core Sagnac interferometer sensors with a Raman-Erbium fiber laser

This work experimentally demonstrates a long-range optical fiber sensing network for the multiplexing of fiber sensors based on photonic crystal fibers. Specifically, six photonic crystal fiber sensors...

Polarization instability of ultrashort pulses as a source of vectorial supercontinuum

Polarization instability of ultrashort light pulses, giving rise to vectorial supercontinuum generation, is demonstrated using a subwavelength-core, highly birefringent, normally dispersive optical fiber....

Raman spectroscopic investigation of the interaction of Enterococcus faecalis and vancomycin – Towards a culture-independent antibiotic susceptibility test

Characterization of optical nonlinearity of a photonic crystal fiber in the spectral domain by cross-phase modulation using a pulsed pump

We report a cross-phase modulation (XPM) method to characterize optical nonlinearity of a photonic crystal fiber (PCF) in the spectral domain, C-band, by using a pulsed pump laser and a continuous wave...

Widely tuneable fiber optical parametric amplifier for coherent anti-Stokes Raman scattering microscopy

We present a narrow-bandwidth, widely tunable fiber laser source for coherent anti-Stokes Raman scattering (CARS) spectromicroscopy. The required, synchronized, two-color pulse trains are generated by...

Screening of plasmonic properties of composed metal nanoparticles by combinatorial synthesis in micro-fluid segment sequences

A micro-flow-through system comprising a manifold for segment generation and mixing, a set of PC-controlled syringe pumps for fluid actuation and an optical multi-channel system for particle characterization...
