Yb Fiber Amplifier

In brief ytterbium doped fiber amplifier.

Yb fiber amplifier.

Giles model ybdfa available in. The input and output fiber connector keys are aligned to the slow axis of the fiber. 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. Erbium ytterbium co doped fiber amplifiers eydfa are typically used in high power optical amplifiers.

Ytterbium fiber amplifier with integrated pre amplifier for scientific applications the cyfa pb series continuous ytterbium doped fiber amplifier are designed for continuous wave operations in the 1 0 μm range and deliver up to 42 dbm of saturated output power. The beam cleanup effect in the large mode area step index fiber. This means that in the unpumped state such amplifiers exhibit some losses caused by the active ions. 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.

Only when a certain excitation level is exceeded does actual amplification take place. Gain and noise spectra of ytterbium doped fiber. 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. The dynamic of mode interaction has been carefully studied.

Most fiber amplifiers e g. This demo investigates the peculiarities of gain and noise spectra of yb doped fiber amplifiers with 975 and 910 nm pump. Here we discuss the main features that influence design and possible applications of ytterbium doped fiber amplifiers. Output light from the amplifier has a polarization extinction ratio of 20 db.

Optilab provides eydfa up to 43 dbm available in single mode sm large mode area lma and polarization maintained pm fiber options. Yb raman fiber amplifier yrfa is a compact setup that can be applied to achieve high power narrow linewidth or special wavelength lasers. 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.
