ABSTRACT

We investigate different ways of controlling the soliton explosions in passively mode-locked fiber lasers through management of the system parameters. Assuming a set of reference values for these parameters, we find that the number of soliton explosions increases with the magnitude of fiber anomalous dispersion. The soliton explosions are suppressed and the stationary pulse width is reduced for relatively low absolute values of dispersion. Similar effects can be achieved using relatively high values of the nonlinear gain. The suppression of soliton explosions is also observed for low absolute values of the nonlinear gain saturation and in situations of relatively high linear losses.

抽象的

我们研究了通过系统参数的管理来控制被动锁模光纤激光器中孤子爆炸的不同方法。假设为这些参数设置了一组参考值，我们发现孤子爆炸的次数会随光纤异常色散的大小而增加。对于相对较低的色散绝对值，孤子爆炸得到抑制，固定脉冲宽度减小。使用较高的非线性增益值可以实现类似的效果。对于非线性增益饱和的低绝对值和相对较高的线性损耗，也可以观察到孤子爆炸的抑制。
