摘要
系统地研究了传输ＣＯ２激光用的新型光纤材料ＧｅＯ２－Ｓｂ２Ｏ３－Ｋ２Ｏ玻璃空芯光纤的光学特性。通过理论计算，得到了该材料ｎｒ＜１的波长范围，消光系数Ｋ和损耗系数ａ，通过工艺和材料的选择，使ａ理论值达到０．０５ｄＢ／ｍ。同时讨论了ＨＥ１１，ＴＭ０１，ＴＥ０１模式损耗和频率的关系。
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.
