【摘要】 <正> The .Er3+-Yb3+-doped fiber has a broadened absorption spectrum, which means the pumping sources can work efficiently from 810 to 1100nm. Among them 980nm is the maximum.absorption (10 dB/km) wavelength. By energy transferring and multiphoton process, the visible and ultraviolet radiation occurs when the Er3+-Yb3+-doped fiber is pumped by the laser at 980-nm band. Further researches on the mechanism of the fluorescence of Er3+-Yb3+-doped silica fiber pumped by Ti: A12O3 tunable laser at 980-nm band are helpful to
