Precision Brachytherapy Device for Esophageal Cancer
This invention is a novel brachytherapy multiple radiation seed delivery device. The device was designed to deliver twice the amount of radiation dose to cancerous tissues via radiation seeds, for patients with esophageal cancer. Background: Brachytherapy is a form of radiation therapy in which small radioactive seeds are placed near cancerous tissue...

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...
