摘　　要：受激布里渊散射(SBS)是窄线宽高功率光纤放大器输出功率的主要限制因素。介绍了目前国内外主要的SBS抑制方案及其研究进展,重点介绍了通过相位调制等方法展宽种子激光线宽以及施加温度、应力梯度和声场裁剪等改变布里渊增益谱的SBS抑制方法。对各种SBS抑制方案进行了对比和总结,为相关研究提供参考。Stimulated Brillouin scattering（SBS） is the main factor which limits the output power in narrow linewidth high power fiber amplifiers. Present SBS suppression methods and progress at home and abroad are illustrated, phase modulation to broaden the linewidth of the seed laser and the methods through applying gradient of temperature and strain to broaden the SBS gain spectrum are emphatically introduced, as well as some other methods such as acoustically tailored fiber. Finally, different approaches of SBS suppression are summarized and compared, which provides some references in related studies.
