N2 - soliton explosion in mode-locked femtosecond lasers based on a nonlinear amplifying loop mirror for different laser parameters, such as the pump power and the length of the passive fiber of the main loop is studied. By numerical solving of the nonlinear Schrödinger equation the spectral shape evolution and the output pulse energy are obtained for various cycles in the cavity. By examining these results, the appropriate range of each parameter for achieving a stable output pulse are acquired. The results provide better understanding of the extent of the effect of each of the cavity parameter and show how deviation from optimal values ​​may lead to the occurrence of soliton explosions for different rounds.
