«We control the below - threshold harmonic
light emission by using electromagnetic fields
with time - dependent ellipticity, like we have done to the above - threshold high - order harmonics,» said Chang referring to the creation of a 67 - attosecond pulse of

ultraviolet light because the short wavelength
light can interact
with dopants or impurities in the fibers, resulting in so - called «solarization» damage and
extreme losses of beam intensity.
