Used fiber lasers.
A fiber laser or fibre laser in british english is a laser in which the active gain medium is an optical fiber doped with rare earth elements such as erbium ytterbium neodymium dysprosium praseodymium thulium and holmium they are related to doped fiber amplifiers which provide light amplification without lasing fiber nonlinearities such as stimulated raman scattering or four wave.
