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...

Novel Approach for Making Optical Fibers
Researchers at the University of Arizona College of Optical Sciences have developed a means of increasing power output in single mode fiber lasers by significantly increasing the mode area available for doping, thus providing higher power in shorter fiber lasers. Instead of the conventional refractive index relationship between the cladding (outer)...

Novel Method of Generating Nearly Non-Diffracting Beams
Researchers at the University of Arizona have developed a method to efficiently generate high power Bessel-like beams using methods that are significantly simpler than those commonly used. The new method allows fine tailoring of output beam characteristics and works over a large range of wavelengths or with white light sources. This novel method provides...
