“…Current state-ofthe-art mode-locked silica-fiber lasers support a pulse energy of the order of microjoules and a peak power of the order of megawatts with the help of dispersion management. 17 However, unlike silica fiber, fluoride fiber engineering remains an open problem, and current techniques cannot support the GVD engineering of fluoride fibers. It is critical to solve the dispersion-management problem of MLFFLs for pulse-energy and peak-power scaling.…”

The mode-locked fluoride fiber laser (MLFFL) is an exciting platform for directly generating ultrashort pulses in the mid-infrared (mid-IR). However, owing to difficulty in managing the dispersion in fluoride fiber lasers, MLFFLs are restricted to the soliton regime, hindering pulse-energy scaling. We overcame the problem of dispersion management by utilizing the huge normal dispersion generated near the absorption edge of an infrared-bandgap semiconductor and promoted MLFFL from soliton to breathing-pulse mode-locking. In the breathing-pulse regime, the accumulated nonlinear phase shift can be significantly reduced in the cavity, and the pulse-energy-limitation effect is mitigated. The breathing-pulse MLFFL directly produced a pulse energy of 9.3 nJ and pulse duration of 215 fs, with a record peak power of 43.3 kW at 2.8 μm. Our work paves the way for the pulse-energy and peak-power scaling of mid-IR fluoride fiber lasers, enabling a wide range of applications.

“…In previously reported studies, Mamyshev technology was used for mostly high-power pulse generation [40]- [42]. Exploiting the self-phase-modulation (SPM)-induced spectral broadening and offset spectral filtering of Mamyshev regeneration, unprecedented nonlinear phase shifts can be obtained, and higher peak powers can be achieved [43].…”

Achieving multi-wavelength synchronous ultra-short pulses with arbitrary wavelength intervals is a difficult problem for fiber lasers. Herein, a laser based on multi-stage cascaded Mamyshev regenerators is proposed as a solution. The regenerators are cascaded to form a single laser cavity, each at a different position within the cavity and corresponding to a different output wavelength. A single pulse oscillating in the cavity has its wavelength sequentially switched by the regenerators. Synchronous multiwavelength pulsed lasers with 5 nm and 0.01 nm output center-wavelength intervals are realized through numerical simulation; the output pulses have 10 nm spectral widths, peak powers of ~0.7 kW, and durations of ~0.4 ps. Design principles, system stability, and the effects of the filter bandwidth, length of single mode fiber and wavelength ordering in the cavity are discussed.

While the performance of mode-locked fiber lasers has been improved significantly, the limited gain bandwidth restricts them to generate ultrashort pulses approaching a few cycles or even shorter. Here we present a novel method to achieve few cycle pulses (~5 cycles) with ultra-broad spectrum (~400 nm). To our best knowledge, this is the shortest pulse width and broadest spectrum directly generated from fiber lasers. It is noteworthy that a dramatic ultrashort pulse evolution can be stabilized in a laser oscillator by the unique nonlinear processes of a self-similar evolution as a nonlinear attractor in the gain fiber and a perfect saturable absorber action of the Mamyshev oscillator.
