Bound-State Pulses in a Mamyshev Oscillator

Abstract

We demonstrate the generation of bound-state pulses in a fibre Mamyshev oscillator by properly adjusting the pump powers. Our results would give some new insights into the pulse dynamics in Mamyshev oscillators.

Generation of High‐Peak‐Power Femtosecond Pulses in Mamyshev Oscillators: Recent Advances and Future Challenges

“…There are two injection methods. The first method entails coupling the seed source with the MO via a coupler, as adopted for all‐fiber MO [ 106,122,123,126 ] or almost all‐fiber MO (where only the filter comprises a free‐space optical filter and collimator); [ 36,55,112 ] the second method involves inserting the external seed source into the cavity via the grating. [ 34,58,77,107,108,125,126 ]…”

[34,58,77,107,108,125,126] Thus far, many researchers have considered that the bandwidth and peak power of the pulses from the seed source are critical factors in determining whether the pulses can span the passband of filters.…”

“…[17,19,34] Furthermore, NPE is unstable in large-scale application environments owing to its sensitivity to the random birefringence of fibers. [34][35][36] The transmission curves of artificial SAs including NOLM, NALM, and NPE are sinusoidal functions related to peak power. 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.…”
