摘要/Abstract

摘要： 首次将Raman光纤放大技术与波长调制技术相结合，使用Raman放大器将近红外激光进行了功率放大，并将放大后的激光应用于远距离天然气管道泄漏遥测中。通过测试Raman光纤放大器在1650nm波段的性能，发现Raman光纤放大器输出功率为Pout时为保证输出信号不发生形变所需的种子光源调制频率f大于0.158×Pout-0.8值，并以此为基础实现了500m远距离的激光遥感探测，为下一步在机载平台上开展天然气泄漏激光遥测技术研究提供了实验基础。

Abstract: The combine of Raman fiber amplification technique with wavelength modulation technique was reported in this paper. The near-infrared laser was amplified by Raman amplifier and was used for the long-distance remote detection of nature gas pipeline leak. Raman fiber amplifier performance was tested at 1650nm band, We found that the modulation frequency of seed laser was greater than 0.158×Pout-0.8 in order to ensure the output signal has no deformation when the output of Raman fiber amplifier was Pout.On this basis, 500m long distance remote detection was realized. And this experiment prepared the basis for next step air-borne detection of nature gas pipeline leak.
