Ytterbium Fiber Laser Wavelength

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 fiber laser wavelength.

Ytterbium can also easily be incorporated into the material used to make the laser. The review is focused primarily on the main fiber laser. Our patented figure 9 technology delivers reliable and consistent mode locking which is ideally suited to ensure long term stable operation. 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.

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. A tunable dual wavelength ytterbium doped fiber ring laser based on sagnac interferometer is proposed and experimentally demonstrated. 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.

These fibers manufactured by n. Erbium fiber lasers emit at 1530 to 1620 nm which is an eye safe wavelength range. 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. 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.

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 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. Thorlabs offers state of the art ytterbium doped optical fibers for optical amplifiers ase light sources and high power pulsed and cw fiber laser applications operating with powers in the milliwatt to 100 w range and emitting in the 1000 1100 nm wavelength region. Thorlabs y fi femtosecond ytterbium fiber laser is a high peak power nir laser that emits clean ultrafast pulses centered at 1035 nm.
