Detection of Nano-Oxidation Sites on the Surface of Hemoglobin Crystals Using Tip-Enhanced Raman Scattering
Hemoglobin nanocrystals were analyzed with tip-enhanced Raman scattering (TERS), surface-enhanced resonance Raman scattering (SERRS) and conventional resonance Raman scattering (RRS) using 532 nm excitation....
PublikationenFibers and fiber-optic components for high-power fiber lasers
The major challenge in the development of monolithic kW class CW fiber lasers is the efficient conversion of pump photons into a high brightness laser beam under the constraints of heat management, long...
PublikationenImproving archaeological site analysis: a rampart in the middle Orkhon Valley investigated with combined geoscience techniques
The Orkhon Valley in Central Mongolia has joined the World Heritage list in 2004. It hosts multiple archaeological sites from Palaeolithic to Recent which allow reconstructing the settlement history in...
PublikationenDirect and absolute absorption measurements in optical materials and coatings by laser induced deflection (LID) technique
Different strategies of the laser induced deflection (LID) technique for direct and absolute absorption measurements are presented. Besides selected strategies for bulk and coating absorption measurements,...
PublikationenFast wavelength switching of a single-frequency disk laser amplifier
For special applications in spectroscopy, tunable single-frequency lasers are required to excite selectively relevant molecules. Amplified Yb:YAG disk lasers provide one opportunity for such lasers with...
PublikationenLaser induced deflection (LID) method for absolute absorption measurements of optical materials and thin films
We use optimized concepts to measure directly low absorption in optical materials and thin films at various laser wavelengths by the laser induced deflection (LID) technique. An independent absolute calibration,...
PublikationenExperimental characterization of bi-directional terahertz emission from gold-coated nanogratings
The THz radiation emission of Au coated nanogratings (fused silica substrate, 30 nm Au layer thickness, 500 nm grating constant) upon fs laser irradiation (785 nm, 150 fs, 1 kHz, 1 mJ/pulse) is observed...
PublikationenDisruption-free imaging by Raman spectroscopy reveals a chemical sphere with antifouling metabolites around macroalgae
Investigations of the surface chemistry of marine organisms are essential to understand their chemically mediated interactions with fouling organisms. In this context, the concentration of natural products...
PublikationenPressure and temperature characterization of two interferometric configurations based on suspended-core fibers
Fabry–Pérot cavity (FPC) made of SCF spliced in-between segments of single-mode and hollow-core fiber is proposed. The interferometric signals are generated by the refractive-indexmismatches between...
PublikationenControl of vortex pair states by post-deposition interlayer exchange coupling modification
In this work we report on both, the global and the micromagnetic properties of interlayer exchange coupled spin systems. We apply ion irradiation as a post-deposition method to modify the coupling strength...
