Ytterbium Fiber Laser

Ytterbium doped laser crystals and glasses have a number of interesting properties which differ from those of e g neodymium doped gain media.

Ytterbium fiber laser.

They have a very simple electronic level structure with only one excited state manifold 2 f 5 2 within reach from the ground state manifold 2 f 7 2 with near infrared or visible photons pumping and amplification involve transitions between. For applications like atomic trapping or interferometry where a linear polarization is needed then the cyfl kilo polarization is highly stable. Ytterbium lasers are highly efficient have long lifetimes and can generate short pulses. 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.

Coming as an entirely integrated turnkey benchtop which can be driven. In this paper we summarize the fundamental properties and review the latest developments in high power ytterbium doped fiber ydf lasers. Reliability and maintenance free are defining this single laser. The ytterbium fiber laser can be randomly or linearly polarized.

With 170 fs pulse widths 20 w average output power and a tunable repetition rate from 1 to 10 mhz this fiber laser enables a. The review is focused primarily on the main fiber laser.
