SAN ANTONIO, Texas, Feb. 20 -- Southampton Photonics Inc. (SPI) and the Optolectronics Research Centre at the University of Southampton have reported 3.5 W of output power at 980 nm from a jacketed air-clad ytterbium-doped fiber laser. The report was made at Advanced Solid-State Photonics 2003 last week in San Antonio. According to SPI, attempts to produce a single-mode 980 nm fiber laser have been stymied because the dopant of choice, ytterbium, stubbornly reabsorbs light generated at 980 nm and emits at around 1040 nm. The company said it employed a threefold solution to the problem: First,...Read full articleRelated content from Photonics MediaArticlesFiber Oscillator Extends Femtosecond Lasing to VIS-Based ApplicationsFemtosecond (fs) fiber oscillators are a standard technology used to generate fs laser pulses.
