Expansible Ascending Aortic Graft
This technology offers an expansible ascending aortic graft that allows for gradual expansion in systole and recoil in diastole, reducing blow flow turbulence and low-flow areas.
Background:
Patients who suffer from senile aortic valve stenosis often require aortic valve replacement. In many patients, concomitant aneurysmal disease requires the...

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...
