提出并实现了一种基于四波混频效应的室温多波长掺铒光纤激光器（EDFL）方案，其波长间隔小于均匀展宽线宽。首次利用高非线性光子晶体光纤（HNL-PCF）和取样光纤光栅（SFBG）实现了稳定的连续波掺铒光纤激光器。我们进一步将四波混频诱导MW-EDFL自稳运转的思想推广到多波长锁模光纤环形激光器中，以产生超短、超快、多波长的同步脉冲源。ITU-T标准上的2和4波长，信道间隔为100 GHz，可在10 GHz同时成功锁模，无增益竞争。
In this paper, we propose and demonstrate a novel room temperature multiwavelength erbium-doped fiber laser (EDFL) scheme with the wavelength spacing less than homogeneous broadening linewidth based on the inter-channel four-wave mixing (FWM). A stable CW MW-EDFL is firstly implemented based on a length of high nonlinear photonic crystal fiber (HNL-PCF) and sampled-fiber Bragg grating (SFBG). We further extend the idea of FWM induced self-stable operation of MW-EDFL to the multiwavelength mode-locking fiber ring laser to generate ultra-short, ultra-fast, multiwavelength and synchronized pulse sources. 2 and 4 wavelengths anchored on ITU-T standards with 100 GHz channel spacing are successfully mode-locked at 10-GHz simultaneously, without gain competition.
