窄线宽光纤激光器及其在光纤传感中的应用

简要介绍了窄线宽激光器技术的现状。针对国内市场对进口窄线宽光纤激光器的依赖，研制了具有自主知识产权的分布反馈光纤激光器样机，突破了有源相移光纤光栅制作技术、隔声隔振封装和有效的功率放大等技术问题，样机功率达到35 mW，线宽小于3 kHz，相对强度噪声低于-115 dB/Hz，主要技术指标已基本接近NKT和NP等先进的国外产品。将样机应用于分布式光纤振动传感系统中，良好地实现了施加信号的解调，信噪比和稳定性完全满足应用要求，并且系统成本远低于进口产品。

Abstract

The current situation of narrow line-width lasers is briefly introduced. In view of the domestic market dependence on imports of lasers a homebred distributed feedback fiber laser with narrow line-width is realized by developing active phase-shifting fiber grating fabrication technology, solving the sound insulation and vibration isolation package technology, and designing a power amplification optical path of single pump. The prototype power is 35mW, linewidth is less than 3 kHz, relative intensity noise is less than -115 dB/Hz. The main technical indicators are close to advanced foreign products such as NKT and NP. The prototype is applied to the distributed optical fiber sensing system, it can realize good sensing signal demodulation, and the use system is much lower than imported products.
