The solution given by the stationary point of the Hamiltonian allowed us to predict the different limitations for the fundamental-soliton process such as dispersive wave generation or multipulse breakdown. We then theoretically and experimentally put in evidence the different domains of stability of these regimes and the hysteresis phenomenon which based on metastability. The experience was based on high gain passively modelocked femtosecond lasers using new ytterbium doped materials and fast semiconductor saturable absorber. We observed, for the first time to our knowledge, dispersive wave generation and multisoliton breakdown and metastable regimes in a femtosecond oscillator using an Yb:doped crystal such as Yb:BOYS and Yb:SYS.
