Chirped pulse amplification in an erbium-doped fiber oscillator/ erbium-doped fiber amplifier system [PDF]
Optics Communications, 1994 Abstract Chirped pulse amplification in erbium fibers is demonstrated. A passively mode locked erbium-doped fiber laser source provides the seed pulses for an erbium-doped fiber amplifier. The system produces femtosecond pulses at a repetition rate of 33 MHz with an energy content as high as 1.4 nJ.

Erbium doped random fiber laser and fiber mixing effect [PDF]
2017 19th International Conference on Transparent Optical Networks (ICTON), 2017 We demonstrate an active random fiber laser by directly pumping a 100 m erbium-doped fiber at 980 nm wavelength, with a fiber loop mirror forming a half-open cavity. Random lasing with competing spectral modes in the range from 1535 nm to 1560 nm is achieved, with the maximum lasing slope efficiency around 10%.
