摘要/Abstract

摘要： 报道了一种全光纤超宽带光谱的类噪声脉冲锁模光纤激光器。为了加宽锁模光谱，利用腔内色散管理和非线性技术，使在58m腔内具有小的反常色散，平均色散系数为0.12 ps/nm/km。实验获得了超过1300nm--1750nm超宽带光谱锁模类噪声脉冲，光谱20-dB带宽达到362nm，3-dB带宽达到102nm。类噪声脉冲的光谱宽度远超过掺铒光纤的增益带宽。

Abstract: The experiment is reported an all-fiber super-broadband noise-like pulse mode-locked fiber laser. To broaden the spectrum of noise-like mode-locked pulse, we managed the nonlinear and dispersion in the cavity. The average dispersion parameter is in the smaller anomalous dispersion regime with 0.12 ps/nm/km in the 58m cavity. The experiment achieved a super-broadband noise-like mode-locked pulse from 1300nm to 1750nm, 20 dB bandwidth of 362nm and 3 dB bandwidth of 102 nm. The spectrum bandwidth of the noise-like pulse greatly exceeds the gain bandwidth of the EDF.
