Numerical investigations on off-resonant pumped Er3+:Yb3+-codoped fiber amplifiers

Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO®/Europe-EQEC)
25.-29. Juni
Type: Konferenzbeitrag
We report a shooting-method to numerically solve a coupled 2-level Er3+:Yb3+-system and demonstrate that pumping single-frequency EYDFAs in MOPA configuration around 950nm rather than 976nm increases the Yb3+-ASE threshold while maintaining short fibre lengths.
