“…For example, the soliton self-frequency shift [67] can efficiently red-shift pulses across a large fraction of the near-infrared and even into the mid-infrared [68]. The soliton self-frequency shift has been demonstrated in a Mamyshev oscillator [69], but additional work is needed to stabilize a high-energy, single-pulse state. Due to the favorable scaling of the soliton area theorem at longer wavelengths, approaches such as this one may provide a route to the highest performance in the mid-infrared.…”

Ultrafast fiber lasers have the potential to make applications of ultrashort pulses widespread - techniques not only for scientists, but also for doctors, manufacturing engineers, and more. Today, this potential is only realized in refractive surgery and some femtosecond micromachining. The existing market for ultrafast lasers remains dominated by solid-state lasers, primarily Ti:sapphire, due to their superior performance. Recent advances show routes to ultrafast fiber sources that provide performance and capabilities equal to, and in some cases beyond, those of Ti:sapphire, in compact, versatile, low-cost devices. In this paper, we discuss the prospects for future ultrafast fiber lasers built on new kinds of pulse generation that capitalize on nonlinear dynamics. We focus primarily on three promising directions: mode-locked oscillators that use nonlinearity to enhance performance; systems that use nonlinear pulse propagation to achieve ultrashort pulses without a mode-locked oscillator; and multimode fiber lasers that exploit nonlinearities in space and time to obtain unparalleled control over an electric field.

“…For the conditions described above, the oscillator does not start from noise. Self-pulsation originating from amplified spontaneous emission (ASE) has been predicted [13] and demonstrated in long cavities (∼km) with highly nonlinear fibers (HNLF) [14,15]. Starting is favorable in these cavities owing to the narrow filter separation, along with the possibility for sufficient nonlinear phase accumulation by even low-power fluctuations in the long HNLF.…”

“…Devices based on reamplification and reshaping have been considered as an alternative for the generation of short pulses [13][14][15]. This approach relies on selfphase-modulation (SPM) induced spectral broadening and offset spectral filtering, as proposed originally by Mamyshev for signal regeneration [16].…”

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.

“…It is expected that larger BPFs, discarding less spectral components, lead to a better efficiency without compromise on the pulse shape, contrary to regenerative sources solely based on SPM. 23 In future work, the influence of cascaded Raman scattering could be investigated, as well as the potential of this architecture to operate with rare-earth doped fibers rather than with Raman pumping. We believe that an experimental implementation of such a cavity is possible based on the numerical results presented in this work with a Raman pump or with another normally dispersive gain medium.…”

Self-pulsating lasers based on cascaded reshaping and reamplification (2R) are capable of initiating ultrashort pulses despite the accumulation of large amounts of nonlinearities in all-fiber resonators. The spectral properties of pulses in self-similar propagation are compatible with cascaded 2R regeneration by offset filtering, making parabolic pulses suitable for the design of a laser of this recently introduced class. A new type of regenerative laser giving birth to similaritons is numerically investigated and shows that this laser is the analog of regenerative sources based solely on self-phase modulation and offset filtering. The regenerative similariton laser does not suffer from instabilities due to excessive nonlinearities and enables ultrashort pulse generation in a simple cavity configuration.
