Passively Q-switched Nd:YAG laser with single-walled carbon nanotube in heavy water

Abstract Carbon nanotubes in heavy water (deuteroxide, D 2 O) dispersion was fabricated and used as absorber in Q-switched Nd:YVO 4 laser for the first time to the best of our knowledge. Such liquid absorber has the virtues of good optical transparency, high heat dissipation and non contact damage. The shortest pulse width of the Q-switched laser is 709 ns, corresponding to 80 kHz repetition rate. The maximum output power of passively Q-switched laser is 214 mW.
