Pump and signal power combiners for high - power fiber amplifier applications
In this work we present the results of our research on a pump power combiner fabrication process in configuration (N+1)×1. Our fabrication method is based on tapering a fiber bundle consisting of 6 multimode fibers and one signal fiber. We present the results on fabrication power combiners based on single mode fibers and large mode area fibers for the signal. Pump power combiners are one of the...
متن کاملPower Thresholds and Pump Depletion in Brillouin Fiber Amplifiers
The Brillouin fiber amplifier (BFA) has been used in Brillouin optical time (frequency) domain analyzer based sensors. The performance of this sensor depends on pump depletion which occurs when the threshold is reached and when the Brillouin gain is saturated. Although threshold definitions are common for Brillouin fiber generators (BFG), there is no explicit threshold definition for BFA. More ...
متن کاملHigh peak power Ytterbium doped fiber amplifiers
1 Abstract We have tested a series of Ytterbium doped large core fibers operating near 10Kpps and producing pulses of approximately 1ns. We have achieved 850μJ/pulse resulting in peak powers in excess of 2MW with 0.4ns pulses and near diffraction limited beams. In another fiber, we have achieved over 1.5mJ/pulse with pulses of 900ps corresponding to 1.65MW of peak power and M of 2.5. In the lat...
متن کاملMode competition in high power fiber amplifiers.
Using a beam propagation model of Yb3+ doped, CW fiber amplifiers we show that gain saturation by a strong fundamental mode significantly suppresses the growth of higher order modes with parallel polarization, but enhances the growth of higher order modes with perpendicular polarization. We quantify this effect in straight and bent fibers, with full core or restricted area doping.
متن کاملMode instability in high power fiber amplifiers.
For powers exceeding a sharp threshold in the vicinity of several hundred watts the beam quality from some narrow bandwidth fiber amplifiers is severely degraded. We show that this can be caused by transverse thermal gradients induced by the amplification process.
