Unique temperature sensing characteristics of CO2-laser-notched long-period fiber gratings

Long-period fiber gratings (LPFGs) are written by use of a focused CO2 laser beam to notch periodically on the surface of optical fibers. Temperature characteristics of the CO2-laser-notched LPFG are investigated...

Optical fiber sensors using hollow glass spheres and CCD spectrometer interrogator

Hollow glass micro-spheres, firstly used to make fiber optic sensors for high hydrostatic pressure, have been interrogated using a high-resolution CCD-based spectrometer, to give far better precision than...

Extending the narrow-bandwidth tunability of a thin disk Yb:YAG laser regenerative amplifier

Optical fiber Bragg grating hydrogen sensor based on evanescent-field interaction with palladium thin-film transducer

Fiber Bragg grating (FBG) sensors in single-mode optical fibers are widely applied for measurement of temperature and strain. If exposing FBG sensors to an external analyte by planar side-polishing technique...

Opportunities of fiber optic sensors and their applications-Editorial

Highly germanium and lanthanum modified silica based glasses in microstructured optical fibers for non-linear applications

Different contrast information obtained from CARS and nonresonant FWM images

We demonstrate that coherent anti-Stokes Raman scattering (CARS)microscopy can be used not to obtain vibrational contrast related to a particular chemical species only, but furthermore, it directly yields...

Enzyme-induced growth of silver nanoparticles studied on single particle level

Based on their interesting properties, metal nanoparticles show the potential as an analytical tool in electronic (Burmeister et al. 2004), optical (Yguerabide and Yguerabide 1998), and catalytic applications...

Higher borides and oxygen-enriched Mg-B-O inclusions as possible pinning centers in nanostructural magnesium diboride and the influence of additives on their formation

Investigation of substitution effects on novel Ru – dppz complexes by Raman spectroscopy in combination with DFT methods

We present a combined Raman–density functional theory (DFT) study of novel dipyridophenazine (dppz) derivatives and their Ru–bipyridine complexes. Our results show that the molecular architecture of...
