Femtosecond Fiber Laser Ushers in New Class of Visible Sources

Facebook X LinkedIn Email
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 alternative due to their ruggedness, reliability, small footprint, efficiency, lower cost, and high...Read full article

    That term pertaining to the spectral region that can be perceived by the eye.
    wavelength
    Electromagnetic energy is transmitted in the form of a sinusoidal wave. The wavelength is the physical distance covered by one cycle of this wave; it is inversely proportional to frequency.
