摘要
利用１．４７μｍ及１．４５μｍ半导体激光器泵浦的掺铒光纤放大器进行了实验研究。结果表明，用１．４５μｍ半导体激光器泵浦掺铒光纤也能对信号光放大。用１．４５μｍ和１．４７μｍ半导体激光器双向泵浦掺铒光纤，获得了２７ｄＢ的增益。
in this paper,the Er3+-doped optical fiber amplifiers(EDFA's) have beeninvestigated experimentally, which are pumped by LDs at wavelengths of 1.45μm and1.47 μm.The results show that the signal light can also be amplified by the EDFA pumpedat wavelength of 1.45μm.A gain of 27 dB has been obtained for the EDFA's forwardsand backwards pumped at wavelengths of 1.45μm and 1.47μm.
