Heavily Er3+-doped TeO2–BaF2–La2O3–LaF3 (TBLL) glasses with low hydroxyl absorption (αOH−≈0.025cm−1 ) and high glass transition temperatures (Tg437℃) were prepared. The Raman spectra and differential scanning calorimetry (DSC) curves were measured to characterize the structural...

Beneficial from the development of femtosecond laser direct writing technique, the fabrication of Bragg gratings inside a fiber with low photosensitivity like active fiber becomes possible. In this paper, we fabricate erbium-doped fiber Bragg gratings (EDFBGs) using femtosecond laser...

Zinc-potassium germanate glasses with nominal composition 50 % GeO2+25 % ZnO+25 % K2CO3 (GZK) and obtained through melt-quenching technique, exhibits superior properties to silicate glasses, widely used as laser light absorbers. These GZK glasses are obtained at lower melting temperatures,...

Wire-feed laser additive manufacturing is an emerging fabrication technique capable of highly automated large-scale volume production that can reduce both material waste and overall cost while improving product lead times. Quality assurance is necessary for implementation into critical...

Laser Powder Bed Fusion (L-PBF) enabled Additive Manufacture (AM) of high field side lower hybrid current drive launcher components from Glenn Research Copper 84 (GRCop-84), a Cr2Nb (8 at. % Cr, 4 at. % Nb) precipitation hardened alloy with a yield strength of 500 MPa and ultimate tensile...

Carbon thin film deposition was carried out with nanosecond or femtosecond laser ablation from two different sp2-bonded carbon targets, in particular highly oriented pyrolytic graphite (HOPG) and glassy carbon (GC). Raman measurements indicated that theses as-deposited films are amorphous carbon...

The effectiveness of the electrochemical WO 3 -modification as a method for improving the photoactivity of native air-formed TiO 2 layers and the way in which a mild laser treatment influences the photoelectrochemical performances of the thus obtained WO 3 /TiO 2 systems were investigated. At...
