A Cellular Key Adaptation Aiding Seedling Survival in Nutrient-Limited and Drought Conditions
This invention describes a newly identified unicellular structure in Phaseolus vulgaris, referred to as the “hooked hair.” It features a unique pointed hook morphology and appears during early seedling development, prior to the emergence of root hairs or above-ground trichomes. Observed in the hypocotyl-radicle junction region below-ground,...

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...
