摘　　要：首先对光纤中受激布里渊散射的耦合波方程进行了离散化,然后利用MATLAB编程对受激布里渊散射光存储过程进行了数值求解,并从理论上对控制光的时间线型和光谱线型对光存储的影响进行了研究。虽然在受激布里渊散射光存储的原理中,读脉冲和写脉冲在光存储中所起的作用不同,但是理论分析却没有看到读写脉冲的差异。计算还表明,当控制脉冲的谱足够宽时,控制脉冲时间线型上的差别对存储结果并无明显影响。啁啾高斯型和矩形控制脉冲由于其宽谱线型可以得到较好的存储结果。The coupled wave equation in the optical fiber based on stimulated Brillouin scattering（SBS） is discretized,the light storage process via SBS is solved by MATLAB,and the effect of the tem poral line profile and spectral line profile of the control-light on the light storage is studied.The read pulse and write pulse play a different role in light storage,but the differences of these can not be found in the theory analysis.The calculations show that the differences of the temporal line profile of the con trol pulse do not obviously affect the stored results.The chirped Gaussian pulse and rectangular pulse can get the best storage because of their wide spectrum.
