We demonstrate passive mode-locking of a bismuth-doped fiber laser using a singlewall nanotube-based saturable absorber. Stable operation in the all-normal dispersion and average soliton regime is obtained, with an all-fiber integrated format. © 2010 Optical Society of America.

We compare experimental results showing stable dissipative-soliton solutions exist in mode-locked lasers with ultra-large normal dispersion (as large as 21.5 ps2), with both the analytic framework provided by Haus' master-equation and full numerical simulations. © 2010 Optical Society of America.

We report the generation of 420 fs pulses of 1.56 μm light from a mode-locked ultrafast laser inscribed Er-doped waveguide laser. Passive mode-locking was achieved using a carbon nanotube saturable absorber. © 2010 Optical Society of America.

A Graphene-based saturable absorber is fabricated using wet chemistry techniques. We use it to passively mode-lock an Erbium doped fiber laser. ~500fs pulses are produced at 1560nm with a 5.2nm spectrum bandwidth. © 2010 Optical Society of America.

Dynamic nonlinear absorption of composite-type single-wall carbon nanotube saturable absorbers is characterized using both femtosecond and picosecond pump pulses. Results are compared with numerical simulations based on two commonly used saturable absorber models. © 2010 Optical Society of America.
