摘　　要：包层光剥离器(CLS)是保证高功率全光纤激光器稳定性与光束质量的核心器件,有效剥除包层光是光纤激光器全光纤化、工程化的重要步骤。详细阐述了CLS制备技术的研究现状,并将其分为基于折射效应、吸收效应、散射效应3种CLS制备技术,分析了各种CLS制备技术的特点。该研究为未来可实现低温升系数、高衰减系数的高功率CLS制备技术提供了参考。The cladding light stripper （CLS） is a key device to guarantee the stability and beam quality of high-power all fiber lasers. It is an especially important step to effectively strip the cladding light for all fiber lasers and its engineering. We present a detailed discussion about the latest progress of the fabrication technology Of CLS, which is classified three types based on refraction effect, absorption effect and scattering effect. The characteristics of various techniques to manufacture CLS are analyzed. Some suggestions are put forward to achieve high power cladding light strippers with low temperature rise coefficient and high attenuation coefficient in the future.
