【Abstract】 With Methods of semiclassical theory and rate equation, the principle and characteristics of erbiumdoped fiber samplifications pumped with CW and pulse light sources are ana(?)yzed in this paper. The relation between the optimal fiber length and pump po wer, doped density and the connection of the gain with the fiber leng(?)h, pump power are presented. The threshold values of pump pow rs under the conditions of CW and pulse pump light sources are calculated. The optimal pump light frequencies are pointed out too.更多还原
