在具有大法向平均色散和大净腔色散的锁模光纤激光器中，对具有准矩形光谱分布的鲁棒耗散孤子分子进行了数值研究和实验观察。这些DSM具有独立发展的相位，脉冲持续时间T-0约为20ps，峰间分离约为8T(0)。在实验室条件下，提出的激光器提供振动DSM的振荡幅度小于峰值分离的百分之一。数值模拟表明，DSM具有频谱调制模式的特征，其调制深度约为3db的平均值。实验观测结果与数值预测结果非常吻合。
The robust dissipative soliton molecules (DSM's) exhibiting as the quasirectangular spectral profile are investigated numerically and observed experimentally in mode-locked fiber lasers with the large normal path-averaged dispersion and the large net cavity dispersion. These DSM's have an independently evolving phase with a pulse duration T-0 of about 20 ps and a peak-to-peak separation of about 8T(0). Under laboratory conditions, the proposed laser delivers vibrating DSM's with an oscillating amplitude of less than a percent of peak separation. Numerical simulations show that DSM's are characterized by a spectral modulation pattern with about a 3-dB modulation depth measured as an averaged value. The experimental observations are in excellent agreement with the numerical predictions.
