Fibercore’s SM Erbium/Ytterbium Doped Fiber (DF1500Y) is a Single-Mode (SM) Erbium (Er) and Ytterbium (Yb) doped fiber, providing extremely high levels of pump absorption and emission around the telecoms C and L band windows. The fiber can be used for lower power fiber lasers, pre-amplifiers and Amplified Spontaneous Emission (ASE) light sources. The high absorption is ideal for applications requiring short gain lengths, for example femtosecond mode-locked ring lasers.
The mixture of Erbium and Ytterbium extends the 915nm pump absorption band to 980nm with a relatively flat absorption rate until the 980nm peak. This allows low cost, non-stabilized 940nm pumps to be used where variations in the pump wavelength with temperature will have a much smaller effect on the output power than pumping at 980nm.

 

Advantages:
• Extremely high pump absorption for short length amplifiers
• Relatively flat pump absorption region around 940nm to allow use of low-cost non-stabilized pump diodes
• Suitable as a pre-amplifier before CP1500Y
