Fluorogallate glass is a favorable kind of material for opticalfiber lasers with transmitting infrared light at longer wavelength and lower phonon energy.
Opticalfiber can be used to transmit near-infraredoptical signal instead of traditional complex system, then the structure would become miniaturization.
近红外波长光信号利用光纤传输，替代了传统的复杂光路系统，使器件结构小型化。
