A sort of nontrivial competition between the excited state absorption (ESA) and optical gain is shown and interpreted for 9 m-long optical fiber. Using a typical SiO2:Nd3+ fiber we observe an interesting nonmonotonic dependence of the gain on signal (probe beam) intensity with substantial contribution of the ESA. This behavior is simulated via kinetic analysis.
