受激布里渊散射（SBS）可以是光纤通信系统中的限制非线性，可以提供光放大，或者可以充当光载波滤波器。然而，SBS的分析处理已被限制在未耗尽的泵制度，只有数值分析可用于当泵耗尽是显着的。特别地，斯托克斯线宽的变窄是众所周知的，然而在高增益、耗尽泵浦条件下的变窄的抑制还没有被处理。我们提出了一个启发式的分析，以量化泵耗尽，准确地预测实验观察到的线宽最小值。
Stimulated Brillouin scattering (SBS) can be the limiting nonlinearity in an optical fiber communications system, can provide optical amplification, or can act as an optical carrier filter. However, the analytical treatment of SBS has been limited to the undepleted pump regime and only numerical analysis is available for when the pump depletion is significant. In particular, the narrowing of the Stokes linewidth is well-known, yet the suppression of narrowing under high-gain, depleted-pump conditions has not been treated. We present a heuristic analysis to quantify pump depletion, which accurately predicts an experimentally observed linewidth minimum.
