摘要 由文献［１］所给Ｅｒ3+掺杂光纤的孤子传输放大方程，对分布放大情况，给出透明传输时的最佳泵浦功率。将其与实验结果比较，证明理论与实验符合很好。对考虑激发态吸收时的最佳泵浦的研究指出，激发态吸收将严重消耗泵浦功率，提高基态量子转移效率可减小激发态吸收的影响。 Abstract From the amplification equation of solitons propagating in Er3+-doped optical fibers given in reference[1]，this paper gives the optimal pumping power for the transparent transmission in the case of distributed amplification. It is shown that the theory is in good agreement with experimental results given previously. The investigation on the optimal pumping in which excited-state absoption is considered indicates that the excited-state absoption seriously damp the pump power, but increasing the auantum transition efficiencv of around-state, can weaken the influence of the excited-state absoption. 作者及机构信息 赵阳, 杨淑雯 1. 深圳大学新技术研究中心 Authors and contacts ZHAO YANG, YANG SHU-WEN 1. 深圳大学新技术研究中心 参考文献 施引文献
