Optically uniform carbon nanotube-polyimide nanocomposite: application to 165 fs mode-locked fiber laser and waveguide

Optically uniform carbon nanotube-polyimide nanocomposite saturable absorber is obtained for the first time using a block-copolymerized soluble polyimide. With this material we demonstrate pulse-shortening,165 fs mode-locked fiber laser and waveguide. (2 pages)
