摘　　要：对传输紫外激光用空芯光纤结构进行了研究。铝膜是从紫外到红外都有很高反射率的理想材料,用它来研制的空芯光纤的直线损耗和弯曲损耗均较小。在铝膜上涂覆设计厚度的低折射率膜可进一步提高系统的反射率,增加传输效率,并保护铝膜免受大气侵蚀。The structure design of hollow waveguides for ultraviolet laser is studied. Aluminum film is the only material with high reflectivity from ultraviolet to infrared. Both straight and bending loss of this kind of hollow waveguides are small. Adding a pair of designed thickness film, which one is of high refractive index and the other is of low refractive index, will increase the reflectivity. At the same time,transmission efficiency also can be raised and aluminum film can he protected from air erosion.
