    Delivery of 1.9 mu m - laser radiation using air-core Bragg fibers

  • Original language description

    In this paper we have investigated Bragg fibers for the 1.94 mu m laser-radiation delivery generated by a thulium fiber laser with a maximal continuous output power 50W. For such investigation laboratory-designed and fabricated hollow-core Bragg fibers have been employed with different diameters of 5, 40, 56 and 73 mu m surrounded by three pairs of circular Bragg layers. Fundamental optical characteristics such as overall transmittance, attenuation coefficient, bending losses, and delivered spatial beam profiles at the wavelength of 1.94 mu m for all tested fibers are reported and summarized in this contribution. In the case of laser radiation delivery with the intensity of 65 kW/cm(2), the lowest attenuation coefficient of 1.278 dB/m was determined for the Bragg fiber with the inner air-core diameter of 56 mu m. Moreover, the bending losses for a small bend diameter of 15 mm reached 0.177 dB only. However delivered laser radiation was highly multimode character.
