We report a simple way to fabricate a high optical quality single wall carbon nanotubes (SWNTs) polyvinyl alcohol (PVA) composite. The composites demonstrate strong saturable absorption at ∼1.5μm, the spectral range for optical communications. These are used as mode-lockers in a fiber laser. We achieve ∼713 fs pulse generation and up to 8 mW output power.
