The conditions are identified, under which a figure-of-eight all-polarisation-maintaining fibre laser with two independently pumped active media, each in one of the two cavity loops, generates soliton molecules with adjustable number of solitons in the molecule. The soliton count in the molecule may be reproducibly set between 2 and 6 by adjustment of the ratio of the pump powers of the active media. The average duration of the autocorrelation function of a single soliton is 11.6 ps, the repetition rate of the pulse train is 14.19 MHz, and its average spectral width is 10 nm. An analysis of the map of the mode-locked regimes set by different ratios of the pump source powers has shown that there exist two separate areas, one corresponding to generation of noise-like pulses and the other, to generation of soliton molecules. We believe that our findings will extend the application area of soliton molecules and will further bring a new insight into understanding of soliton molecule ...

保持全偏振的改良8字形光纤激光器作为孤子分子的来源

确定了条件，在此条件下，具有两个独立泵浦的活性介质的八维全偏振保持光纤激光器分别在两个腔环之一中生成孤子分子，该孤子分子中的孤子数可调。通过调节活性介质的泵浦功率的比例，可以将分子中的孤子数可重复地设置在2到6之间。一个孤子的自相关函数的平均持续时间为11.6 ps，脉冲序列的重复频率为14.19 MHz，其平均光谱宽度为10 nm。对由不同比例的泵浦源功率设定的锁模状态图的分析表明，存在两个独立的区域，一个对应于产生类噪声脉冲，另一个对应于孤子分子。
