摘　　要：类噪声脉冲(NLP)是锁模激光器在一定条件下生成的一种特殊脉冲,具有能量高、脉宽宽、相干性低等特点。近年来,由于稀土元素掺杂技术、锁模技术和光纤放大技术的不断发展以及抽运能量的不断提升,类噪声脉冲光纤激光器得到了迅速发展。基于此,描述了使用不同锁模技术、工作在不同色散区的类噪声脉冲光纤激光器。依据其脉冲产生机理、脉冲光学性质等特点进行分类叙述,综述了国内外这一领域的研究现状及进展。最后,对近年来类噪声脉冲激光器在生产实践中的具体应用进行了简要阐述。Noise-like pulses （NLP） are a kind of special pulse with high energy, wide spectral bandwidth, and low coherence, which are generated from the passively mode-locked fiber lasers under certain conditions. In recent years, NLP fiber lasers have developed rapidly because of the fast development of doping technology, mode-locking technology, fiber amplification technology, and the improvement of pump energy. Based on this, NLP fiber lasers with different mode locking techniques operated in different dispersion regimes were summarized. The NLP fiber lasers were classified based on the discrepancy in its pulse generation mechanism and optical properties. Research status and progress of the fiber lasers at home and abroad was reviewed. Finally, the application of the fiber lasers in production practice was briefly depicted.
