Raman and FTIR imaging of lung tissue: bronchopulmonary sequestration

Bronchopulmonary sequestration (BPS) involves abnormal pulmonary tissue lacking trancheobronchial connection and having a separate vascular supply that arises from the thoracic or abdominal aorta. For...

Synthesis Mechanisms of Organized Gold Nanoparticles: Influence of Annealing Temperature and Atmosphere

We report on the synthesis of organized arrays of gold (Au) nanoparticles on thermally oxidized Si wafers using sputtering as a metal deposition method in combination with sphere lithography. This simple...

Identification and differentiation of single cells from peripheral blood by Raman spectroscopic imaging

Medical diagnosis can be improved significantly by fast, highly sensitive and quantitative cell identification from easily accessible body fluids. Prominent examples are disseminated tumor cells circulating...

Employing polyethylene as contacting agent between ATR-crystals and solid samples with hard surfaces

Using a single crystal of fresnoite (Ba2TiSiO8), we demonstrate that polyethylene (PE) can be used as a contacting agent to enable the recording of ATR-spectra of materials with hard surfaces. The performance...

Pulse preserving flat-top supercontinuum generation in all-normal dispersion photonic crystal fibers

Supercontinuum (SC) generation in all-normal dispersion photonic crystal fiber under high energy femtosecond pumping is numerically investigated. It is shown that coherent octave spanning SC spectra with...

Influence of Na-related defects on ArF laser absorption in CaF2

Tunable narrow band filter for CARS microscopy

In this letter we present an approach to CARS mi- croscopy, which compromises between fast acquisition rates and the amount of chemical information obtained. By using a light modulator as tunable filter...

Spatially resolved determination of the structure and composition of diatom cell walls by Raman and FTIR imaging

Vibrational spectroscopic imaging has developed into a versatile tool to study the local composition of various materials. Here, we present for the first time that Raman mapping and Fourier-transform infrared...

Dynamics of droplet formation at T-shaped nozzles with elastic feed lines

Generation of green light in a thermally poled silica fiber by quasi-phase-matched second harmonic generation

Thermal poling is an attractive method to induce a nonlinear coefficient in silica materials. We have investigated potential silica materials with respect to their suitability for thermal poling and analyzed...
