Design guidelines for ultrashort pulse generation by a Mamyshev regenerator

We study numerically the possibility of using various gain-switched seed laser pulse parameters and fibers for a low-cost, all-fiber Mamyshev regenerator scheme. find that increasing durations, sufficient spectral broadening will be difficult to achieve in practice careful design system is required function. Furthermore, an optimal input peak power level can defined given fiber duration results from balance competing Kerr effect stimulated Raman scattering. also demonstrate experimental 3 ps generation seeded by 80 diode. Our pave way designing pulse-on-demand picosecond scale sources applications.
