Özet

In present work we developed a simulation model which allows to calculate a fraction of amplified spontaneous emission in continuous wave (CW) Er-Yb co-doped fiber amplifier. The simulation shows that high output power at 1550 nm with reasonably small amount of ASE (0.7%) can be reached at very low, mW-level seed signal with single amplification stage. Based on the simulation results, a medium power (3 W) Er-Yb co-doped fiber laser was demonstrated with only one amplification stage.
