摘　　要：在窄线宽激光器的应用领域中,激光频率稳定度是一个极其重要的指标参数,表征频率稳定的程度。基于被动稳频和主动稳频技术的实质区别——有无稳定的频率参考,主要针对主动稳频技术综述了激光稳频技术的国内外研究进展,包括:根据选用频率标准的不同进行分类;分析了常用的激光稳频技术的原理及达到不同稳频精度的原因;根据国内外关于主动稳频技术的研究报道,将其优缺点进行比较分析。经过反复对比,相位调制光外差(PDH)稳频技术具有明显的优势,可以得到极高的频率稳定度。In many application fields of narrow linewidth lasers, laser frequency stability is an extremely important parameter, and characterizes the degree of frequency stability. Based on the virtual difference between passive frequency stabilization and active frequency stabilization——having stable frequency reference standards or not, laser frequency stabilization techniques are studied, especially for active frequency stabilization： classification is done based on the selection of frequency standards; the theory and reason of reaching different precisions of frequency stabilization technologies commonly used are analyzed; advantages and disadvantages are compared based on reports of the active frequency stabilization at home and abroad. By comparison repeatedly, the PDH technology has obvious advantages, can obtain high frequency stability.
