“…Apparently, a real-time high-resolution spectro-temporal analyzer operating in a continuous mode is yet to be demonstrated for better understanding the nonlinear optical physics as well as optimizing the laser performances. Photonic time-stretch through dispersive chirp has recently been demonstrated as a highthroughput single-shot spectral analyzer [31][32][33] and has greatly enriched researches on nonlinear physics, e.g., supercontinuum generation [34], optical rogue wave observation [24,35,36], soliton explosion [37,38], as well as mode-locking and soliton-molecule formation [39,40]. Despite its superior performance in fs-ps regime, typically for transformlimited short pulses, time-stretch spectroscope (TSS) is inadequate for CW/quasi-CW optical signal, see Appendix 1.…”

Abstract:Spectro-temporal studies on the nonlinear physics of complex laser dynamics are essential in approaching its ultimate performance as well as understanding interdisciplinary problems. Unfortunately, it has long been limited by the insufficient spectro-temporal resolving power of conventional temporal and spectral analyzers, particularly when an indefinite optical signal ensemble contains polychromatic mixtures of continuous-wave (CW) and short pulse. In this work, we propose a real-time optical spectro-temporal analyzer (ROSTA) with three synchronized processing channels (i.e., multi-core) for single-shot studies on laser dynamics. It simultaneously provides temporal resolutions of ~70 ps in the time domain and 10's ns (or 10's MHz frame rate) in the spectral domain, as well as a high spectral resolution for multiscale optical inputs, i.e., ranging from CW to fs pulses. Its nontrivial record length of up to 6.4 ms enables continuous observations of non-repetitive optical events over an extensive time period -equivalent to a propagation distance of ~1900 km. To showcase its practical applications, ROSTA is applied to visualize the onset of passive modelocking of a fiber laser, and interesting phenomena, i.e., evolution from quasi-CW noise burst to strong shock, transition from fluctuation to mode-locking, and coexistence of CW and mode-locked pulses, have been spectro-temporally observed in a single-shot manner for the first time. It is anticipated that ROSTA will be a powerful technology for spectro-temporal optical diagnosis in different areas involving polychromatic transients. 1335-1337 (2008). 11. C. Xu and F. W.

As a type of nonlinear system with complexity, mode-locked fiber lasers are known for their complex behaviour. It is a challenging task to understand the fundamental physics behind such complex behaviour, and a unified description for the nonlinear behaviour and the systematic and quantitative analysis of the underlying mechanisms of these lasers have not been developed. Here, we present a complexity science-based theoretical framework for understanding the behaviour of mode-locked fiber lasers by going beyond reductionism. This hierarchically structured framework provides a model with variable dimensionality, resulting in a simple view that can be used to systematically describe complex states. Moreover, research into the attractors’ basins reveals the origin of stochasticity, hysteresis and multistability in these systems and presents a new method for quantitative analysis of these nonlinear phenomena. These findings pave the way for dynamics analysis and system designs of mode-locked fiber lasers. We expect that this paradigm will also enable potential applications in diverse research fields related to complex nonlinear phenomena.

“…More recently, a different medium for explosions was reported by Broderick et al, namely, a passively mode-locked fibre laser [2]. In 2016, Liu et al showed that in an ultrafast fiber laser, the exploding behavior could operate in a sustained but periodic mode called "successive soliton explosions" [3].…”
