摘要

光纤中的受激拉曼散射是非线性光纤光学领域的重要研究课题之一。研究了掺铪石英光纤及铪铝共掺石英光纤的拉曼散射增强特性,采用785 nm的激发光测量了掺铪石英光纤及铪铝共掺石英光纤的拉曼光谱,并与常规单模光纤的拉曼光谱进行了对比。实验结果表明在光纤中掺杂铪元素或铪铝元素共掺能够明显地增强光纤的拉曼散射强度,并获得很好的拉曼散射增强效果。

Abstract

Stimulated Raman scattering is one of the most important problems in the field of nonlinear fiber optics. The Raman scattering enhancement characteristic of Hf-doped silica fiber and Hf/Al co-doped silica fiber are researched. The Raman spectra of Hf-doped silica fiber and Hf/Al co-doped silica fiber are measured by using 785 nm exciting light, and compared with conventional single-mode fiber (SMF). The experimental results show that Hafnium doping or Hafnium/Aluminum co-doping can enhance the optical fiber Raman scattering intensity, and achieve a good Raman scattering enhancement effect.
