High power resonantly pumped holmium-doped fibre sources

, 2014
Holmium-doped fibres provide a power scalable gain-medium capable of operation at wavelengths beyond 2.05 μm. We discuss and review our approach to the power scaling of pulsed and CW laser sources at 2.1 μm using holmium-doped fibres. This paper outlines

Prospective LCA of E‐Methanol Along the Transformation of Steel Industry

Chemie Ingenieur Technik, EarlyView.
The environmental effects of change in steel production route on e‐methanol production are analyzed as they shift from blast furnace route to direct reduction route. Specific hydrogen demand reduces, as do the avoided CO2 emissions. E‐methanol's overall carbon footprint stays in a narrow range of −1 to −1.1 kg‐CO2‐eq./kg‐methanol.

Revisiting the Nexus Between Trade Liberalisation and Income Inequality: The Case of Sub‐Saharan African Countries

International Journal of Finance &Economics, EarlyView.
ABSTRACT This paper examines the impact of trade liberalisation on income inequality across 24 Sub‐Saharan African (SSA) countries from 2000 to 2020. Using IV‐Tobit and 2SLS models, we consistently find that greater trade openness significantly exacerbates inequality in the region. Critically, we document an inverted U‐shaped relationship between trade

Triple-Clad Fiber Combiner for Holmium-Doped Fiber Lasers Clad-Pumping

Photonics
The development of a high-power 7 × 1 triple-clad fiber combiner aimed at resonantly clad-pump holmium-doped fiber lasers is presented. Thanks to the implementation in the combiner of a low refractive index glass capillary, we show that the developed ...

Clinical Evaluation of the Effectiveness of Digital Peroral Cholangioscopy‐Guided Lithotripsy for Difficult Bile Duct Stones

Journal of Hepato-Biliary-Pancreatic Sciences, EarlyView.
ABSTRACT Background and Aims Peroral cholangioscopy‐guided lithotripsy (POCS‐L) has emerged as a treatment option for difficult bile duct stones (DBDSs), but detailed evidence remains limited. This study evaluated its effectiveness, safety, and risk factors for adverse events (AEs).
