Octave Broadband Supercontinuum Generation in Gas-Filled Anti-Resonant Hollow-Core Fiber

We report on octave broadband supercontinuum generation from ultraviolet to near infrared wavelengths in the fundamental mode of a gas-filled novel low-loss anti-resonant hollow-core fiber having distinct...

Confocal sputtering of (111) orientated smooth gold films for surface plasmon resonance approaches

We report on the influence of sputtering parameters on the microstructural growth of 200 nm thick Au layers and, moreover, on their crystalline, electrical, and optical properties using a confocal sputtering...

Strategies for Isolation and Enrichment of Bacteria for Subsequent Raman Spectroscopic Identification

Fast Isolation Strategies for Microorganisms for Subsequent Raman Spectroscopic Identification

Yb3+-doped rod-type amplifiers with local adiabatic tapers for peak power scaling and beam quality improvement

The use of short local tapers in large mode area fiber amplifiers is proposed for peak power scaling while maintaining good beam quality. To avoid modal distortions, the powder-sintering (REPUSIL) method...

Direct Raman spectroscopic measurements of biological nitrogen (N2) fixation under natural conditions: A novel analytical approach for studying nitrogenase activity

Biological N2 fixation is a major input of bioavailable nitrogen, which represents the most frequent factor limiting the agricultural production throughout the world. Especially, the symbiotic association...

Laser irradiation influence on Si/3C-SiC/Si heterostructures for subsequent 3C-SiC membrane elaboration

The cubic polytype of silicon carbide is a stimulating candidate for Micro-Electro-Mechanical-Systems (MEMS) applications due to its interesting physical and chemical properties. Recently, we demonstrated...

Enhancing photocatalytic hydrogen generation: The impact of the peripheral ligands in Ru/Pd and Ru/Pt complexes

The synthesis, photophysical properties and photocatalytic efficiency of a range of novel supramolecular assemblies of the type [Ru(dceb)2(µ-bisbpy)MCl2](PF6)2 and [Ru(bpy)2(µ-bisbpy)MCl2](PF6)2 (where...

Germania and alumina dopant diffusion and viscous flow effects at preparation of doped optical fibers

We report on germania and alumina dopant profile shift effects at preparation of compact optical fibers using packaging methods (Stack-and-Draw method, Rod-in-Tube (RiT) technique). The sintering of package...
