Narrow Bandwidth Hundreds Picosecond Pulse Fiber Laser Based on Carbon Nanotubes Mode-Locker

0.01 nm, 323 ps passively mode-locked erbium-doped fiber laser(EDFL) based on carbon nanotubes (CNTs) is established with a homemade fiber Bragg Grating(FBG) as the intra-cavity filter. The demonstrated laser characterizes the all fiber configuration and features a simple structure.
