纯硅材料喇曼激光器及硅芯光纤的研究进展

摘要

Silicon material at 1.2 ~ 6.6(xm has high transparency and high Raman gain features, which easily results to stimulate mid-infrared Raman laser in the near room temperature. This paper firstly describes the most concern problem of the nonlinear conversion efficiency of silicon laser. Secondly, it introduces the research by applying pure silicon as Raman laser gain media, and reports the research status. At last, we predict the silicon core optical fiber can be used for newly high-power near-infrared Raman laser as the gain medium.%硅材料在1.2～6.6μm波段有高透明和高喇曼增益的特性,易于在室温条件下激发出近中红外波段喇曼激光.详细阐述了硅激光的非线性转换效率的问题.介绍了采用纯硅材料作为增益介质的喇曼激光器的研究进展,并对研究现状进行了报道.预测硅芯光纤将作为新型大功率近中红外的喇曼激光器的增益介质.
