摘要：

Optical amplification characteristics are studied for Er-doped silica core single-mode fiber amplifiers with different Er concentrations pumped by 1.48 μm wavelength laser diodes. Optical gain drastically depends on Er concentration even when Er concentration is less than 1000 ppm. In the case of the 40 mW incident pump power, the maximum net gain for the 77 ppm Er containing fiber is higher than that for the 970 ppm Er containing fiber by 11.4 dB. © 1990 IEEE
