We present novel carbon-nanotube-based saturable absorbers. Using the low-temperature alcohol catalytic chemical-vapor deposition method, high-quality single-walled carbon nanotubes (SWNTs) were directly synthesized on quartz substrates and fiber ends. We successfully applied the SWNTs to mode lock a fiber laser producing subpicosecond pulses at a 50-MHz repetition rate.

Tsukubo, Ibamki 305-8568, JapmAbstract: A novel passively mode-locked fiber laser is demonstrated using saturable absorber based on sinele-walled carbon nanolubes. This is the first demonseation of an ootical oulsed laser based on carbon -. .nanotube technology.
