Those based on erbium and ytterbium operate on quasi three level transitions neodymium doped amplifiers are a notable exception.
Yb fiber amplifier.
The input and output fiber connector keys are aligned to the slow axis of the fiber.
To achieve low power signals amplification from 1060 to 1090 keopsys proposes a ytterbium doped fiber amplifier.
Output light from the amplifier has a polarization extinction ratio of 20 db.
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.
This demo investigates the peculiarities of gain and noise spectra of yb doped fiber amplifiers with 975 and 910 nm pump.
This means that in the unpumped state such amplifiers exhibit some losses caused by the active ions.
Only when a certain excitation level is exceeded does actual amplification take place.
In brief ytterbium doped fiber amplifier.
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.
Keopsys has designed a particular optical fiber architecture to avoid nonlinear effects that can damage the ytterbium amplifier.
Here we discuss the main features that influence design and possible applications of ytterbium doped fiber amplifiers.
