摘      要：We demonstrate a simple,compact and low-cost mode-locked erbium-doped fiber laser(EDFL)using a single-wall carbon nanotube(SWCNT)poly-ethylene oxide(PEO)composite as a passive saturable absorber(SA).The composite with an SWCNT concentration of 18wt%is prepared by mixing the SWCNT homogeneous solution with a diluted PEO polymer solution.A droplet of the polymer composite is applied on the fiber ferrule end,which is then mated to another clean ferrule connector to construct an *** SA is then integrated into the laser system to self-start stable mode locking at 1557 nm without employing a polarization *** EDFL generates a stable soliton pulse train with a duration of 0.81 ps,repetition rate of 44 MHz and average output power of 92.4μW at a 980 nm pump power of 26.8 *** soliton laser starts to lase at a pump power threshold of 14.6 mW.
