SiO2-Al2O3-La2O3 glass – a superior medium for optical Kerr gating at moderate pump intensity

Novel SiO2-Al2O3-La2O3 (SAL) glass shows a switching efficiency > 70% for dual wavelengths optical Kerr gating (OKG) at 1 TW=cm2 peak intensity IP of the gate pulse. It is steadily increasing with IP,...

Molecular Detection of Bacteria and Decontamination of Water: Molecular Detection of Bacteria and Decontamination of Water: Current trends and future perspectives

Microbial contamination of water resources causes a huge socio-economic impact as illustrated by the frequent outbreaks in developed and resource constrained countries. To combat potential threat an efficient...

Fiber array based hyperspectral Raman imaging for chemical selective analysis of malaria-infected red blood cells

A new setup for Raman spectroscopic wide-field imaging is presented. It combines the advantages of a fiber array based spectral translator with a tailor-made laser illumination system for high-quality...

Role of the Chemical Environment beyond the Coordination Site: Structural Insight into Fe-III Protoporphyrin Binding to Cysteine-Based Heme-Regulatory Protein Motifs

The importance of heme as a transient regulatory molecule has become a major focus in biochemical research. However, detailed information about the molecular basis of transient heme–protein interactions...

Demonstration of >5kW emissions with good beam quality from two different 7:1 all-glass fiber coupler-types

We report on two low-loss 7:1 single-mode to multi-mode fiber coupler-designs generating more than 5 kW of output power. These all-glass fiber-optical devices have the objective to keep the brightness...

High-Brightness Incoherent Combination of Fiber Lasers in 7 × 1 Fiber Couplers at Average Powers > 5 kW

We report on the experimental realization of two different low-loss single- to multimode fiber coupler designs, each combining more than 5 kW of output power. The adiabatic mode evolution in the seven-fiber...

The 2015 super-resolution microscopy roadmap

Far-field optical microscopy using focused light is an important tool in a number of scientific disciplines including chemical, (bio)physical and biomedical research, particularly with respect to the study...

In situ spectroelectrochemical and theoretical study on the oxidation of a 4H-imidazole-ruthenium dye adsorbed on nanocrystalline TiO2 thin film electrodes

Terpyridine 4H-imidazole-ruthenium(II) complexes are considered promising candidates for sensitizer in dye sensitized solar cells (DSSCs) by displaying a broad absorption in the visible range, where the...

Hybrid Optical Fibers – An Innovative Platform for In-Fiber Photonic Devices

The field of hybrid optical fibers is one of the most active research areas in current fiber optics and has the vision of integrating sophisticated materials inside fibers, which are not traditionally...
