A Steerable, Optically Guided System for Detection of Ureteral Injury and Ureteral Catheterization
This technology is a therapeutic and diagnostic one-time-use device to place a ureteral catheter or stent without fluoroscopic guidance. Enhancements to the device may allow detection of injury to the ureter via Optical Coherence Tomography (OCT) and treatment of nephrolithiasis via laser lithotripsy. This small-diameter ureteral catheter or stent comprises...

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...
