As the spectral width (Full width half maximum: FWHM) range from 6nm to 60nm, the simulation results show that the effect of the variation of the FWHM upon the output is small. When only the Verdet constant is considered, the output increased slowly with the increase of the FWHM. The simulation results are verified by the experiment.

当光源光谱宽度在6nm到60nm之间变化时，不同谱线宽度光源对系统输出影响的仿真结果表明：光源谱宽变化对系统输出的影响相对于其单色模型来说，相对变化小于10~(-3)，因此光源谱宽变化对系统输出的影响较小；如果完全消除了线性双折射和反射相移，则系统输出随光源谱宽的增加有微弱的增加：由于Verdet常量的影响最大，所以系统输出随光源谱宽的增加有微弱的增加；实验结果验证了该结论。
