Zusammenfassung: | 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 multi-wavelength 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. |
