In this paper, we demonstrate a widely tunable passively mode-locked fiber laser covering the C or L band with carbon nanotube films. Our results show that the saturable absorber incorporating nanotubes (SAINT) has potential for constructing widely tunable passively mode-locked fiber laser.

Key words: tunable lasers, mode-locked lasers, fiber lasers, saturable absorber, carbon nanotube films
