Abstract

Insufficient coherence of the laser sources used in Stimulated Brillouin amplification setups not only leads to reduced gain but also to source-induced noise, affecting their performance. This paper investigates the impact of laser phase noise on the Brillouin gain, and in particular on its probability distribution function, for different values of the coherence time and fiber length. It is shown that for equally phase-noised pump and probe, their (separately) induced gain and gain fluctuations are different. The results, obtained numerically and validated experimentally, may contribute to the judicial choice of laser sources in practical Brillouin-based systems.
