Generation of noise-like pulses and soliton rains in a graphene mode-locked erbium-doped fiber ring laser
Abstract: We demonstrate the generation of noise-like pulses (NLPs) and soliton rains in a graphene saturable absorber mode-locked erbium-doped fiber laser. Typical NLPs are obtained at a proper pump power and in a cavity polarization state. The soliton rain operation with multiple solitons can be achieved by finely adjusting the cavity polarization state. In addition, distinctive multi-soliton interactions are observed and investigated, including the fundamental mode-locking and multiple pulses. The experimental results can help further understand nonlinear pulse dynamics in ultrafast optics.

摘要：本文研究了基于石墨烯可饱和吸收体锁模的掺铒光纤激光器中类噪声脉冲以及孤子雨的产生。在合适的泵浦功率和腔偏振态下，实验获得典型的类噪声脉冲。通过精细调节腔偏振态，激光器可实现多孤子的孤子雨状态运转。此外，观察并研究了独特的多孤子相互作用，包括基频锁模和多脉冲。实验结果有助于进一步理解超快光学中的非线性脉冲动力学过程。
