Yb Fiber Amplifier

The ytterbium doped fiber amplifier offers a number of attractive features including a broad gain bandwidth and a high efficiency due in large part to its freedom from various competing.

Yb fiber amplifier.

This demo investigates the peculiarities of gain and noise spectra of yb doped fiber amplifiers with 975 and 910 nm pump. Gain and noise spectra of ytterbium doped fiber. Output light from the amplifier has a polarization extinction ratio of 20 db. Yb raman fiber amplifier yrfa is a compact setup that can be applied to achieve high power narrow linewidth or special wavelength lasers.

The beam cleanup effect in the large mode area step index fiber. Here we discuss the main features that influence design and possible applications of ytterbium doped fiber amplifiers. However ytterbium doped fiber lasers and amplifiers operating near 1 micrometre wavelength have many applications in industrial processing of materials as these devices can be made with extremely high output power tens of kilowatts. Our proprietary design ensures high gain and excellent po.

In this letter we realized a high power yrfa with seed wavelengths of 1090 nm and 1150 nm tandem pumped by a 1018 nm fiber laser. This means that in the unpumped state such amplifiers exhibit some losses caused by the active ions. Giles model ybdfa available in. The pump current of the ytterbium doped fiber amplifier is adjustable through the instrument s front panel allowing the user to vary the gain and output power of the amplifier.

The dynamic of mode interaction has been carefully studied. The input and output fiber connector keys are aligned to the slow axis of the fiber. In brief ytterbium doped fiber amplifier. Optilab provides eydfa up to 43 dbm available in single mode sm large mode area lma and polarization maintained pm fiber options.

Most fiber amplifiers e g. The ytterbium doped fiber amplifier offers a number of attractive features including a broad gain bandwidth and a high efficiency due in large part to its freedom from various competing processes seen in other rare earth dopants. Those based on erbium and ytterbium operate on quasi three level transitions neodymium doped amplifiers are a notable exception. To achieve low power signals amplification from 1060 to 1090 keopsys proposes a ytterbium doped fiber amplifier.

Keopsys has designed a particular optical fiber architecture to avoid nonlinear effects that can damage the ytterbium amplifier.
