Numerical and experimental investigations of stimulated Brillouin scattering signal amplification in standard single-mode fibers under pump depletion show that while gains are reduced, the same orthogonal input states of polarization that provide maximum and minimum gain in the undepleted case practically continue to do so in the depleted regime. Using a scaled Brillouin gain coefficient, the power distribution of these max/min polarizations along the fiber can be deduced from a scalar formulation.
数值和实验研究表明，在抽运功率耗尽的情况下，标准单模光纤中受激布里渊散射信号的放大作用。虽然增益降低了，但在未耗尽情况下提供最大和最小增益的相同正交偏振输入状态，实际上在耗尽情况下仍然如此。通过使用比例化的布里渊增益系数，可以从标量公式推导出这些最大/最小偏振沿光纤的功率分布。
