Ytterbium-doped Fiber Amplifiers:Selection of Pump Wavelength |
|
| Abstract: | Gain, saturation and noise characteristics of ytterbium doped fiber amplifiers (YDFAs) with different pump wavelengths are discussed. It is pointed out that the YDFAs pumped at 975 nm, free from self saturation induced by 975 nm ASE, have some advantages, as compared with YDFAs pumped at 910 nm. |
