Abstract :
Carbon nanotubes in heavy water (deuteroxide, D2O) dispersion was fabricated and used as a saturable absorber for mode locking in a fiber laser. Such liquid absorber has the virtues of good optical transparency, high heat dissipation, and high damage threshold. A passively mode locked fiber laser with it was demonstrated. The pulsewidth is 306 fs with the maximum average output power of 20 mW. The center of the wavelength is 1560 nm with 15.2-nm spectral width.
