We investigated a dispersion-managed, passively mode-locked, ultrashort-pulse, Er-doped fiber laser using a polyimide film containing dispersed single-wall carbon nanotubes (SWNTs) and examined the dependence on net cavity dispersion and output coupling ratio using normal-dispersion fibers and a variable output coupler. For the dissipative soliton mode-locking condition, we achieved a pulse energy of 3.5 nJ and an average power of 114 mW, the highest values yet reported for an SWNT fiber laser under single-pulse operation.
