Abstract
In this work we present a new design of Er/Yb co-doped fiber amplifier with controlled amplified spontaneous emission (ASE) at 1 μm. The Yb-ASE is controlled by stimulating a laser emission at 1064 nm in the amplifier, by providing a positive 1 μm signal feedback loop. The results were discussed and compared to a conventional amplifier setup without 1 μm ASE control. We have shown, that applying a 1064 nm signal loop in an Er/Yb amplifier can increase the output power at 1550 nm and provide stable operation without parasitic lasing at 1 μm.
