TLDR
In this paper, the threshold of the stimulated Brillouin scattering (SBS) in a long single-mode fiber excited with a multimode pump laser was investigated, and it was theoretically shown that when the mode spacing of the pump laser is larger than the Brilloughin-gain bandwidth, each Stokes mode experiences gain from only one pump mode and builds up independently in the long fiber with long interaction length.Abstract:
The threshold of the stimulated Brillouin scattering (SBS) in a long single-mode fiber excited with a multimode pump laser is investigated. It is theoretically shown that when the mode spacing of the pump laser is larger than the Brillouin-gain bandwidth, each Stokes mode experiences gain from only one pump mode and builds up independently in a long fiber with long interaction length. On the basis of this fact, the SBS threshold with an N-multimode pump with equal intensities is predicted N times greater than that with a single-mode pump. The theoretical predictions are verified by an experiment in which the number of longitudinal modes of a 1.32-μm Nd:YAG laser is changed.read more
