为了建立高可靠性和高抗干扰性能的拉曼激光雷达系统，提出了一种新型的全光纤光谱拉曼激光雷达系统，该系统由光纤耦合器、光纤带宽滤波器和光纤F-P滤波器组成全光纤光谱系统。在光纤F-P滤波器设计及其传输分析的基础上，将光纤耦合器串联设计为光纤分路器，既实现了激光雷达回波输入输出的光纤耦合，又实现了三个光纤通道的最佳能量输出比。提出用光纤带宽滤波器代替二向色镜，光纤带宽滤波器与光纤F-P滤波器构成二级级联滤波系统，实现了感兴趣光谱的精细提取和对弹性散射信号的高抑制率。初步测试结果表明，三个输出端口的能量比为5：2.5：2.5，两个光纤带宽滤波器的中心波长分别为606 nm和660 nm，带宽为20 nm，带外抑制率> 0.5%，满足设计要求。该设计和结果将为后续全光纤光谱系统的集成和实验提供可靠的依据。
Aimed to establish a Raman lidar system with high-reliability and high anti-interference performance, an newly all-fiber spectroscopic Raman lidar system was proposed for atmospheric water vapor measurement, in which optical fiber couplers, fiber band-width filters and fiber F-P filters constitute the all-fiber spectroscopic system. On the basis of the design of fiber F-P filters and its transmission analysis, the series connection of optical fiber coupler is designed as fiber optics splitter, which is not only to obtain fiber coupling of the input and output of lidar returns, and also to achieve the optimal energy output ratio at three fiber channels. Furthermore, fiber band-width filters are proposed to replace the dichroic mirrors, and the structure of fiber band-width filters and fiber F-P filters is to constitute the secondary cascade filter system, achieving the fine extraction of interested spectrum and high rejection rate to elastic scattering signals. Preliminary test results indicated that, the energy at the three output ports is %sim;5: 2.5: 2.5, and the two fiber band-width filters are provided with the central wavelength of 606nm and 660nm, the bandwidth of 20nm, and the out of band inhibition of >0.5%, which met the design requirements. The design and results will provide a reliable basis for the integration and experiment of the subsequent all-fiber spectroscopic system.
