摘　　要：提出了一种基于商售光纤构建的适用于精密光谱光频梳应用的100 MHz重复频率色散管理孤子光纤激光器的设计方案。通过采用低负色散光纤调控重复频率、高正色散光纤增大腔内脉冲呼吸比,构建了重复频率为108 MHz、中心波长为1550 nm的基于正色散掺铒光纤的色散管理孤子光纤激光器,该激光器腔内净色散为-0.0023 ps^2,直接输出脉冲宽度为70 fs,经光纤压缩后脉冲宽度为48 fs,且脉冲中心波长处在1550 nm。A design scheme of dispersion managed soliton fiber lasers with 100 MHz repetition frequency suitable for constructing the optical frequency comb applied in precision spectroscopy is presented based on common commercial optical fibers. By adjusting the repetition frequency with low negative dispersion fibers and increasing the respiration ratio of the intra-cavity pulse with high positive dispersion fibers, a dispersion managed soliton fiber laser with repetition frequency of 108 MHz and center wavelength of 1550 nm based on positive dispersion erbium-doped fiber is built. The intra-cavity net dispersion of the laser is -0.0023 ps2. The direct output pulse width is 70 fs. The pulse width is 48 fs after fiber compression, and the pulse center wavelength is 1550 nm.
