近几年,随着光纤激光技术的飞速发展与日益急迫的应用需求,2.0μm超短脉冲掺铥光纤激光器的研究取得了较大的进展和突破。比如,被动锁模掺铥光纤振荡器输出最窄脉冲宽度达到了119fs;最高单脉冲能量达到了8.75nJ;超短脉冲掺铥光纤放大器最高输出单脉冲能量达到了156μJ;2.0μm超短脉冲掺铥光纤激光器也从原来的空间结构开始向全光纤结构转变,以及从实验演示逐步向工业实 In recent years, with the rapid development of fiber laser technology and the increasingly urgent application requirements, the research on 2.0 μm ultrashort pulse-doped fiber laser has made great progress and breakthrough. For example, the pulse width of the passive mode-locked fiber oscillator reaches 119fs, the maximum single-pulse energy reaches 8.75nJ, the maximum output single-pulse energy reaches 156μJ for the ultrashort pulse-doped fiber amplifier,铥 fiber laser from the original structure of the space began to change all-fiber structure, and from the experimental demonstration gradually to the industrial real
