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...

Fast Quantitative Magnetic Resonance Imaging
This technology is a novel Quantitative Magnetic Resonance Imaging (QMRI) method based on the application of a linear combination of RF excitation pulses and MR measurement sensitizing strategies following a nulling sequence. Multiple differentiated measurements can be made over the course of each repetition of the sequence. In theory, this allows for...

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...
