    Abstract

    To achieve the flexible transmission of an ultraviolet laser, a hollow antiresonant fiber with seven capillary tubes in the cladding was fabricated. The outer diameter of the fiber is 95 μm, and the core diameter is 11 μm. The average diameter of the cladding is 5 μm, and the average wall thickness is 319 nm. Two ultraviolet laser beams with wavelengths of 266 nm and 355 nm can be simultaneously guided by the fiber with transmission losses of 0.25 dB/m and 0.8 dB/m, respectively. The bending loss in the two transmission bands at a bending radius of 5 cm is 0.05 dB/m at 266 nm and 0.023 dB/m at 355 nm. The low bending sensitivity is due to the small core diameter of the fiber. This allows further miniaturization of the device. The antiresonant fiber is expected to play an important role in laser transmission and ultraviolet laser spectroscopy.
