摘 要：<正> In this paper a new kind of mid - infrared fiber material is reported. The reflective coefficients （R） of glasses in the system Na2O - ZnO - GeO2-SiO2-PbO have been measured .the refractive index becomes less than unity at 1180 - 900cm-1 range because of the existence of anomalous dispersion. The optical losses of hollow: waveguides were calculated,the predicted losses at 940cm-1are 0. 65 and 0. 081B/ m as the inner diameter of fiber is 0. 5 and 1. 0-mm respectively. The glasses can be used as the cladding materials of hollow waveguides for transmitting CO2 laser from the measurements of characteristic temperatures , coefficient of expansion and chemical durability.
