Abstract :
We have investigated both theoretically and experimentally a method to increase the peak power in femto-second fiber laser by using a low-doped long-length gain medium. The accumulated nonlinear phase shift as well as its threshold value for single pulse operation was studied and used to explain the robustness of such cavity against multipulsing and optical wave breaking.
