摘要

首次将Raman光纤放大技术与波长调制技术结合,使用Raman光纤 放大器对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1650 nm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与Pout满足特定的线性关系, 并以此为基础实现了500 m远距离激光遥感探测,为在机载平台上 开展天然气泄漏激光遥测技术研究提奠定了基础。

Abstract

Combining Raman fiber amplification technique with wavelength modulation technique for the first time, the power of near-infrared laser is amplified by Raman optical fiber amplifier, and the laser amplified is used for the long-distance remote detection of nature gas pipeline leak. Raman fiber amplifier performances are tested at 1650 nm range. It’s found that when the output power of Raman fiber amplifier is Pout, f and Pout meet certain linear relationship in order to ensure non-deformation of the output signal. Based on it, 500 m long distance laser remote sensing detection is realized. It lays the foundation for research of laser remote sensing technology of natural gas leakage on airborne platform.
