Abstract

We demonstrate a Q-switched Ytterbium-doped double-cladding fiber laser based on single-walled carbon nanotubes as saturable absorbers. The pure single-walled carbon nanotubes were directly deposited on the one end of the Ytterbium-doped double-cladding fiber by optically driven deposition method. A linear-cavity was employed and a 1.5m long Ytterbium-doped double-cladding fiber played as the gain fiber. The Ytterbium-doped double-cladding fiber was pumped by a 976-nm fiber coupled diode laser. The maximum output power of 1.3W was obtained at the wavelength of 1070nm. The pulse-repetition rates were tuned from 9.1 KHz to 60 KHz when the pump powers were changed from 1.85W to 10W and the shortest pulse duration was around 600ns.
