Paper Abstract

We report a saturated absorption characteristic of carbon nanowall and Q-switched laser operation using carbon nanowall saturable absorber. Carbon nanowall is vertically aligned nanographite sheets on Si substrate synthesized by plasma-enhanced chemical vapor deposition method. A polyimide thin film, with incorporated carbon nanowall, coated by spin-coating method, is used as saturable absorber. Linear absorption spectrum of carbon nano-walls was observed without absorption peak wavelength range from 1000 to 2000nm. Modulation depth of carbon nanowall saturable absorber was measured with wavelength of about 1560nm. Q-switch laser operation with carbon nanowall saturable absorber and erbium doped optical fiber was demonstrated.
