Yb Fiber Amplifier

Yb raman fiber amplifier yrfa is a compact setup that can be applied to achieve high power narrow linewidth or special wavelength lasers.

Yb fiber amplifier.

Most fiber amplifiers e g. Our proprietary design ensures high gain and excellent po. 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. In brief ytterbium doped fiber amplifier.

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. Output light from the amplifier has a polarization extinction ratio of 20 db. 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.

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. The dynamic of mode interaction has been carefully studied. Here we discuss the main features that influence design and possible applications of ytterbium doped fiber amplifiers. The input and output fiber connector keys are aligned to the slow axis of the fiber.

Erbium ytterbium co doped fiber amplifiers eydfa are typically used in high power optical amplifiers. Keopsys has designed a particular optical fiber architecture to avoid nonlinear effects that can damage the ytterbium amplifier. To achieve low power signals amplification from 1060 to 1090 keopsys proposes a ytterbium doped 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 processes seen in other rare earth dopants.

Only when a certain excitation level is exceeded does actual amplification take place. Those based on erbium and ytterbium operate on quasi three level transitions neodymium doped amplifiers are a notable exception. This demo investigates the peculiarities of gain and noise spectra of yb doped fiber amplifiers with 975 and 910 nm pump. Optilab provides eydfa up to 43 dbm available in single mode sm large mode area lma and polarization maintained pm fiber options.

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.
