Paper Abstract

A new type of the double layers polycrystal dielectric film in the quartz capillary has been fabricated. The first film is composed of nanoscale germanium dioxide obtained from controlling reaction temperature, gas flow rate and the proportion of reactants, and the second film is metal layer that has high refractive index at infrared region. So the dual-layer thin film has very high reflectivity at the wavelength range of 8-11 .6 µ m. The hollow-core optical fiber with this film on inner wall can transmit over 400 watts of cw carbon dioxide laser power or the pulse carbon dioxide laser with pulse width of 0.1 second and peak-power of 1000 watts, and transmission loss is less than O.6dB/m at 10.6 µ m in transmitting high power. The transmitting laser power fibers can be applied in medical treatment, mechanical process or the relevant scientific research etc.
