摘要
搭建了一种集成结构的液芯光纤中红外拉曼激光光源, 利用全光纤结构液芯耦合装置进行抽运注入。将中心波长为1064 nm、重复频率为5 kHz、最大输出功率为55 mW的亚纳秒激光器作为抽运源, 将不同比例的四氯化碳和二硫化碳混合溶液充入中空光纤中, 获得了至少7阶的拉曼信号输出。目前可测得的最长波长为2.08 μm, 拉曼阈值最低为0.3 mW。通过搭建全光纤结构的液芯光纤耦合装置, 获得了90%以上的光纤耦合效率。实验发现利用石英光纤产生的拉曼信号可以对液芯受激拉曼散射的产生起到促进作用。
Abstract
An integrated structure of liquid-core fiber mid-infrared Raman laser source is established, and an all-fiber structure liquid-core coupling device is used to pump injection. A nanosecond laser with center wavelength of 1064 nm, repetition rate of 5 kHz and maximum output power of 55 mW is used as pump source, and a hollow core fiber is filled with the mixture with different proportions of carbon tetrachloride and carbon disulfide. At least seven-order Raman signal is achieved, and the longest wavelength of 2.08 μm and the minimum Raman threshold of 0.3 mW can be measured. The fiber coupling efficiency larger than 90% is achieved when we establish the liquid-core fiber coupling device with all-fiber structure. We also find that the Raman signal generated by silica fiber plays a prominent role in the generation of stimulated Raman scattering.
