| Abstract: | This paper systematically studies the GeO2-Sb2O3-K2O glass hollow-core fiber material used for transmitting CO2 laser. By theoretical calculation, the wave-length range and K value at nr <1, as well as loss coefficient, a= 0. 05 dB/m have been obtained. The relationship between loss and frequency at HEll. TM0l and TE0l modes has been discussed. |
