Abstract

The graphene oxide GO thin film has been obtained by mixture of GO spin coated on substrate of indium tin oxide ITO. The experiment has shown that continuous-wave laser is modulated when the graphene oxide saturable absorber GO-SA is employed in the 1064 nm laser cavity. The shortest pulse width is 108 ns at the pump power of 5.04 W. Other output laser characteristics, such as the threshold pump power, the repetition rate, and the peak power, have also been measured. The results have demonstrated that graphene oxide is an available saturable absorber for 1064 nm passive Q-switching laser.
