“…The demonstrated multi-port real-time observation provides insights into exploring intracavity dynamics in various optical systems, which are helpful to understand the complex transient nonlinear dynamics in the cavity and complete the theories of soliton. On the other hand, it also has promise for studying how the solitons evolve between multiple states in other types of fiber lasers, such as Mamyshev oscillator 42 , bidirectional all-normal dispersion fiber laser 43 , and dissipative soliton resonance generation 44 .…”

Recent advances in real-time spectral measurements of a mode-locked fiber laser have found many intriguing phenomena and which have verified the soliton theory. However, most current results are based on laser single-port observation, and are rarely involved in the cavity evolution, which also has rich nonlinear dynamics according to the soliton theory. Here we present an approach for the intracavitary soliton evolution processes, where spectra from multi-ports are collected in time-division multiplexed sequence to realize synchronous real-time observation. The sinusoidal evolution of the spectral beating is observed clearly, agreeing with the reported prediction. Furthermore, the intracavitary spectral dynamics of the period-doubling bifurcation are also revealed. Our scheme observed the spectral expanding and shrinking alternately and periodically over two round trips, matching well with simulations. This work may open up possibilities for real-time observation of various intracavitary nonlinear dynamics in photonic systems.

“…Multiple dynamic patterns of pulses were observed including single pulses, bound pulses, and HML pulses at different pump powers and filter spectral separations. 73 Although self-starting is desirable in general, it requires NPE, which relies on non-PM fibers that are subject to environmental perturbations.…”

“…The starting of mode-locked operation could be triggered easily by adjusting the waveplates or just by increasing the pump power under suitable parameters of the waveplates and filter spectral separations. Multiple dynamic patterns of pulses were observed including single pulses, bound pulses, and HML pulses at different pump powers and filter spectral separations 73 . Although self-starting is desirable in general, it requires NPE, which relies on non-PM fibers that are subject to environmental perturbations.…”

The nonlinear effect of fiber limits the further increase in pulse energy, and Mamyshev oscillator shows outstanding advantages in managing nonlinearity in waveguide medium, which is now associated with high peak power and high pulse energy. The potential applications of these laser sources based on Mamyshev mechanism have facilitated aggressive research and innovative ideas by researchers around the world. Here, we focus on the modelocked principle and starting dynamics of Mamyshev oscillator. The review of Mamyshev technology is summarized from two starting modes of seed source injection and self-starting. Initial research and significant progress in this field, plus new insights and challenges of Mamyshev oscillator for ultrafast fiber laser technology are analyzed.

“…As a result, they are susceptible to pulse instability and multiple pulses, [ 37 ] and their peak power is limited by the anti‐saturation absorption effect. [ 38 ] In addition, all of the SAs mentioned above have a common disadvantage in that their tolerance of nonlinear phase shift is limited, which restricts the generation of high‐peak‐power femtosecond pulses.…”

Mamyshev oscillators (MOs) have attracted significant attention given their potential in yielding ultrafast lasers with high peak power. Based on step‐like saturable absorbers and self‐similar evolution in the gain fiber, MO technology features an advanced system capable of generating ultrastable femtosecond pulses with ultrahigh peak power. In this review, the principle of MO is presented in terms of their transmission function and tolerance to nonlinear phase shift and recent progress is reported in the advanced output performance of MO, manifested through high peak power, few‐cycles, high repetition rate, and supercontinuum generation. MO with various operation wavelengths (1, 1.5, and 2 μm) are examined, and MO starting methods are fully discussed, followed by a detailed account of diverse potential applications in areas such as biomedical imaging and material processing. Based on current progress, the prospective challenges and future directions of MO are highlighted and discussed.
