SAN JOSE, Calif., Feb. 3 -- Cladding pumped-fiber lasers are producing the high powers required to replace traditional lasers in important application areas, said Johan Nilsson of Southampton Photonics, Inc.(SPI) and the Optoelectronics Research Centre (ORC), University of Southampton, at a presentation last week at Photonics West 2003 in San Jose. Nilsson said his findings enhance the rapid advances being made in optical fiber and pump technology. In published experiments, Nilsson said, over 270 W of single-mode output power at 1080 nm from an ytterbium-doped fiber laser (YDFL), and over 100...Read full articleRelated content from Photonics MediaArticlesPhotonic Wire Bonding: Using Lasers to Integrate LasersJust as electronic integrated circuits have revolutionized computing, photonic integrated circuits (PICs) are poised to transform applications such as high-speed optical communications, optical...Photonics Spectra August 2022 IssueTwo-Photon Holographic Mesoscope Probes Activity Across Large Brain RegionsRecent advancements in two-photon (2P) mesoscopes have extended the field of view (FOV) for deep brain imaging, making it possible to image brain regions as large as 25 mm2.
