Abstract

Soliton explosion and soliton pulsation are among the most intriguing nonlinear dynamics in dissipative systems. In this paper, we construct an ultrafast Yb-doped fiber laser mode-locked by nonlinear polarization rotation (NPR). Up to five nonlinear regimes are observed successively in our device by adjusting two intra-cavity polarization controllers, including stable dissipation solitons, noise-like pulses (NLPs), soliton explosion, soliton pulsation and Q-switched mode-locked (QSML) state. Benefiting from the dispersive Fourier transform (DFT) method, we capture the real-time spectra evolution of those nonlinear dynamics, which can help researcher to better understand different soliton dynamics. Our work will enhance a more comprehensive understanding of nonlinear phenomenon in dissipative systems.

掺镱模式锁定光纤激光器中孤子爆发和脉冲的非线性动力学特性

孤子爆发和孤子脉动是耗散系统中最引人入胜的非线性动力学之一。在本文中，我们构建了一种由非线性偏振旋转（NPR）锁模的超快掺镱光纤激光器。通过调节两个腔内偏振控制器，我们在设备中连续观测到了多达五种非线性状态，包括稳定耗散孤子、类噪声脉冲（NLP）、孤子爆炸、孤子脉冲和调 Q 开关模式锁定（QSML）状态。利用色散傅里叶变换（DFT）方法，我们捕捉到了这些非线性动力学的实时光谱演化，这有助于研究人员更好地理解不同的孤子动力学。我们的工作将加深对耗散系统中非线性现象的全面理解。

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
