Ytterbium Fiber Laser Wavelength

Due to a broad gain bandwidth of ytterbium doped fiber a tuning range of 17 9 nm for single wavelength lasing output and 8 4 nm for dual wavelength lasing have been achieved with side mode suppression ratio higher than 38 db.

Ytterbium fiber laser wavelength.

Ytterbium has none of the self quenching effects that occur in neodymium at high densities which is why neodymium is used in bulk lasers and ytterbium is used in fiber lasers they both provide roughly the same wavelength. Erbium fiber lasers emit at 1530 to 1620 nm which is an eye safe wavelength range. 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. Thorlabs y fi femtosecond ytterbium fiber laser is a high peak power nir laser that emits clean ultrafast pulses centered at 1035 nm.

Also devices containing some kind of laser e g a fiber coupled laser diodes and a fiber amplifier are often called fiber lasers or fiber laser systems. 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. Ytterbium doped laser crystals and glasses have a number of interesting properties which differ from those of e g neodymium doped gain media. In most cases the gain medium is a fiber doped with rare earth ions such as erbium er 3 neodymium nd 3 ytterbium yb 3 thulium tm 3 or praseodymium pr 3 and one.

Ytterbium lasers are highly efficient have long lifetimes and can generate short pulses. These fibers manufactured by n. 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. A tunable dual wavelength ytterbium doped fiber ring laser based on sagnac interferometer is proposed and experimentally demonstrated.

Menlo systems ytterbium based femtosecond fiber laser oscillator integrates the latest developments in fiber technology and incorporates these enhancements into an easy to use product. Ytterbium lasers commonly radiate in the 1 06 1 12 µm band being optically pumped at wavelength 900 nm 1 µm dependently on the host and application. The review is focused primarily on the main fiber laser. Ytterbium can also easily be incorporated into the material used to make the laser.
