Dissipative soliton evolution in ultra-large normal-cavity-dispersion fiber lasers.
Dissipative soliton (DS) evolution in passively mode-locked fiber lasers with ultra-large net-normal-dispersion (as large as 1 ps(2)) is investigated. The proposed DS laser operates on three statuses with respect to the pump power. The DS laser works on a status that is similar to an all-normal-dispersion laser when the pump power is low, whereas it creates a new type of pulses exhibited as the trapezoid-spectrum profile when the pump power is large. The laser cavity emits the unstable pulses between the above two statuses. The cubic-quintic Ginzburg-Landau equation can serve to qualitatively explain our experimental observations.
