Abstract

We present an experimental and theoretical analysis of four-wave-mixing (FWM) in nanosecond pulsed fiber amplifiers FWM leads to a saturation of the in-band amplified pulse energy and to distortions of the spectral and temporal profiles, and it is the main limiting effect in the ~1 ns temporal regime. A simple model considering both Raman and FWM contributions provides a good description of the measured behaviours, allowing optimization and design tradeoffs to be explored for mitigating FWM.
