Ytterbium Fiber Laser

In this paper we summarize the fundamental properties and review the latest developments in high power ytterbium doped fiber ydf lasers.

Ytterbium fiber laser.

The ytterbium fiber laser can be randomly or linearly polarized. The yb 3 ion is used as a doping material in active laser media specifically in solid state lasers and double clad fiber lasers. Ytterbium can also easily be incorporated into the material used to make the laser. For applications like atomic trapping or interferometry where a linear polarization is needed then the cyfl kilo polarization is highly stable.

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. 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. 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. Ytterbium lasers are highly efficient have long lifetimes and can generate short pulses.

Thorlabs y fi femtosecond ytterbium fiber laser is a high peak power nir laser that emits clean ultrafast pulses centered at 1035 nm. Ytterbium doped laser crystals and glasses have a number of interesting properties which differ from those of e g neodymium doped gain media.
