We present an L-band dissipative soliton (DS) fiber laser, which can deliver 87.5 fs pulses at 1.6 μm band. Numerical simulations are used to confirm the DS generation, and prove the pivotal component of the invisible filter with proper bandwidth in the formation of DS pulses. Such a robust, compact ultrafast laser source with higher pulse energy is hence an excellent seed source for L-band amplifiers. The mechanism revealed in the simulations is helpful to develop a unified theory for understanding various mode-locking regimes in normal dispersion lasers.
我们展示了一种L波段耗散孤子（DS）光纤激光器，它能够在1.6μm波段产生87.5 fs的脉冲。通过数值模拟来确认DS的产生，并证明具有适当带宽的隐形滤波器在DS脉冲形成中的关键作用。因此，这种稳健、紧凑且具有更高脉冲能量的超快激光源是L波段放大器的理想种子源。模拟中揭示的机制有助于发展一种统一理论，以理解正常色散激光器中的各种锁模机制。
