“…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.

“…The main limitation of fiber Mamyshev oscillator is that the operation in the anomalous group-delay dispersion (GDD) regime is prohibitive due to the high energy pulse breakup problem. Fiber Mamyshev oscillators to date work either at 1 µm where the normal GDD fiber is readily available [8,[11][12][13] or at 1.5 µm where specialty fibers can be utilized to shift the GDD [14]. Operation at longer wavelengths with Tm-doped silica fiber and Er-doped ZBLAN fiber, characteristic of large anomalous GDD and Kerr nonlinearity, thus poses a nontrivial challenge [9].…”

We present the first design and analysis of a solid-state Mamyshev oscillator. We utilize the phase-mismatched cascaded quadratic nonlinear process in periodically poled lithium niobite waveguide to generate substantial spectral broadening for Mamyshev modelocking. The extensive spectral broadening bridges the two narrowband gain media in the two arms of the same cavity, leading to a broadband mode-locking not attainable with either gain medium alone. Two pulses are coupled out of the cavity and each of the output pulses carries a pulse energy of 25.3 nJ at a repetition rate of 100 MHz. The 10-dB bandwidth of 2.1 THz supports a transform limited pulse duration of 322 fs, more than 5 times shorter than what can be achieved with either gain medium alone. Finally, effects of group velocity mismatch, group velocity dispersion, and nonlinear saturation on the performance of Mamyshev mode-locking are numerically discussed in detail.

We demonstrate a fiber source with the best performance from an ultrafast fiber oscillator to date. The ring-cavity Mamyshev oscillator produces ~50-nJ and ~40-fs pulses. The peak power is an order of magnitude higher than that of previous lasers with similar fiber mode area. This performance is achieved by designing the oscillator to support parabolic pulse formation which enables the management of unprecedented nonlinear phase shifts. Experimental results are limited by available pump power. Numerical simulations reveal key aspects of the pulse evolution, and realistically suggest that (after external compression) peak powers that approach 10 MW are possible from ordinary single-mode fiber. The combination of practical features such as environmental stability, established previously, with the performance described here make the Mamyshev oscillator extremely attractive for applications.
