Fiber laser
From Wikipedia, the free encyclopedia
A fiber laser or fibre laser is a laser in which the active gain medium is an optical fiber doped with rare-earth elements such as erbium or ytterbium. Semiconductor laser diodes are commonly used for pumping fiber lasers. Fiber lasers can have extremely long gain regions. They can support very high output powers because the fiber's high surface area to volume ratio allows efficient cooling, and its waveguiding properties reduce thermal distortion of the beam.
Applications include: telecommunications, networking, spectroscopy, and medicine.
