【摘要】 基于已有理论模型,利用1064nm连续波抽运源在不同抽运光强下对不同长度光纤抽运所产生的受激喇曼散射现象进行数值模拟,并对模拟结果作了分析.研究发现:发生受激喇曼散射现象时,抽运光强和光纤长度发生兑换;能量红移现象普遍存在,包括同阶Stokes光谱内部和不同阶的Stokes光谱之间.抽运光强越大,能量红移现象越明显.更多还原

【Abstract】 The principle and model of stimulated Raman scattering(SRS)are provided.Process of SRS has been deeply analyzed and simulated by injecting the different intensity pump with central wavelength at 1 064 nm into a standard single-mode fiber with different lengths.Through the simulation of SRS,it is found that pump power exchanges with fiber length;the red shift of energy widely exists,including the same grade Stokes spectrum inside and between different grade Stokes spectrums.And the red shift of energy becomes evident with pump intensity increases.更多还原
