摘要
掺铒光纤放大器(EDFA)具有高增益(40—50dB)、宽带宽(-50nm)以及很高的单脉冲饱和能量(-1μJ),因而被认为是放大超短光脉冲的主要器件。围绕如何减轻光纤非线性效应对超短光脉冲放大过程的有害影响,综述了基于EDFA的超短光脉冲放大技术及其进展情况,介绍了最近的研究结果。
Erbium-doped fiber amplifier (EDFA) is considered to be the main device for ultrashort pulse amplification owing to its high gain (40 - 50 dB), broad bandwidth ( -50 nm), and high pulse-saturation energy ( -1μJ). In this paper, ultrashort pulse amplification techniques based on EDFA are reviewed and discussed, with the emphasis on how to reduce the fiber nonlinear effects on the amplification of ultrashort pulse. The latest achievements in this field are also introduced.
