High Power Picosecond Lasers Mode Locked with Carbon Based Absorbers
Single walled carbon nanotubes and graphene oxide are deposited on glass and quartz by vertical evaporation method, respectively. By using single walled carbon nanotubes absorber, passively mode locked NdYVO4 laser is obtained. The maximum output power is 3.6 W, the slope efficiency is 31%, the pulse duration is 7.6 ps and the repetition rate is 75 MHz. By using graphene oxide absorber, passively mode locked NdGdVO4 laser is achieved. The maximum output power is 1.1 W, the slope efficiency is 11.3%, the pulse duration is 4.5 ps and the repetition rate is 70 MHz.
