Enhanced Water Splitting with Protic Buffer/Electrolyte Cocatalysts
This invention is a protic co-catalyst used to increase the rate of electrolysis for splitting water to hydrogen and oxygen in a hydrogen evolving reaction. The co-catalyst is present in the electrolyte and is not consumed during the reaction. The co-catalyst may enhance the efficiency of water-splitting in systems that use a heterogenous catalyst,...

Distributed Feedback Fiber Laser Pumped by Multimode Diode Lasers
Researchers at the University of Arizona College of Optical Sciences and Canada's Carleton University recently succeeded in fabricating high reflectivity (>99%) Fiber Bragg Gratings (FBGs) into phosphate glass fibers using UV light and a phase mask technique. With this new manufacturing technique, fiber lasers can be created as single monolithic...

All-Fiber Multicore Fiber Laser Devices
Researchers at the University of Arizona have developed a compact, power-scalable, alignment-free fiber laser that takes a new approach to stabilizing phase-locked operation of multi-core fiber lasers by completely removing all free space optical components. This high-brightness, all-fiber laser package uses passive optical fiber spliced at both ends...
