We present a detailed description of the methods used in our model of mode instability in high-power, rare earth-doped, large-mode-area fiber amplifiers. Our model assumes steady-periodic behavior, so it is appropriate to operation after turn on transients have dissipated. It can be adapted to transient cases as well. We describe our algorithm, which includes propagation of the signal field by ...
SPIDER operation, started in 2018, pointed out performance-limiting issues caused by the technology employed RF generators, based on tetrode free-running oscillators. One of these limits, namely onset frequency instabilities, prevented operation at full rated power 200 kW. In addition, tetrodes require high voltage to operate, which translates risk flashovers and necessity perform conditioning ...
Optical communication links are usually made with erbium-doped fiber amplifiers, which amplify the signal waves in a phase-insensitive (PI) manner. They can also be made with parametric fiber amplifiers, in which the signal waves interact with idler waves. If information is transmitted using only the signals, parametric amplifiers are PI and their noise figures are comparable to those of erbium...
