Femtosecond Fiber Laser Ushers in New Class of Visible Sources
QUEBEC CITY, July 10, 2023 — Researchers from Laval University reported the development of the first fiber laser that can produce femtosecond pulses in the visible range of the electromagnetic spectrum. Fiber lasers producing ultrashort, bright visible-wavelength pulses could be useful for a variety of biomedical applications as well as other areas such as material processing. Visible femtosecond pulses are usually obtained using complex and inherently inefficient setups. Although fiber lasers represent a promising
