For the fiber coatings used in fiber lasers, the requirements are quite strict with the performances such as refractive index and heat resistance. Currently, this kind of fiber coatings mainly relies on import. In this paper, UV-cured fiber coatings with ultra-low refractive index are prepared by using fluoride diols, IPDI, monofunctional fluorinated acrylate, self-prepared difunctional fluoride acrylate and HEA etc. By changing the ratio of raw materials, different formulas are designed and their performances including viscosity, refractive index, mechanical properties and Tg are investigated. The results show that the prepared coating exhibits ultra-low refractive index, proper viscosity, favorable mechanical properties and heat resistance, which can meet the operating requirements of fiber lasers.
