高保偏光纤前方受激拉曼散射光谱特性的研究

Study of the spectral characters of stimulated Raman scattering in highly elliptical-core optical fibres

系统的研究了石英系高保偏双折射光纤的受激拉曼光谱的特性 ,给出了七级斯托克斯谱和一级反斯托克斯谱 .测试了各级拉曼谱的阈值、谱宽和拉曼增益 。

In this paper, we systematically study the spectral characters of stimulated Raman scattering (SRS) in the birefringence optical-fibre and give seventh-order Stokes and first-order anti-Stokes spectra, then measure the threshold, spectrum width and Raman gain of SRS. At the same time, we make an analysis of the mechanism of energy transmission between each order of the Raman spectra.
