摘要 高功率窄线宽连续光纤激光器在科学研究、工业加工和军事功防领域具有广泛的应用价值。在保证激光器输出质量的前提下,不断提升输出功率是高功率激光器不懈追求的关键目标之一。受激布里渊散射效应是制约激光功率提升的关键因素之一,本文针对受激布里渊散射效应展开,重点介绍基于光谱展宽的非线性效应抑制方法的不同方案与效果,综述利用相位调制展宽种子源光谱的发展历程,分析当前存在的问题并展望该技术的发展前景。 High-power narrow-linewidth continuous-wave fiber lasers have a wide range of application values in scientific research,industrial processing,and military defense.On the premise of ensuring the output quality,continuously improving the output power is one of the key goals of high-power lasers.This research focuses on the suppression of the stimulated Brillouin scattering effect,which is one of the key factors restricting the laser power improvement.Various methods of nonlinear effect suppression and the corresponding performances are introduced,especially the spectral broadening method.In addition,the current problems and the development prospects of this technology are analyzed.
