Abstract

Highlights: Few layers mixed Sb2 Te3 -GO saturable absorber for Q-switched laser is demonstrated. The simply fabrication process and detailed of the parameters is described. Compact passively Q-switched operation of Nd:GGG laser is reported. Abstract: Saturable absorber (SA) based on antimony telluride (Sb2 Te3 )-graphene oxide (GO) had been fabricated. We demonstrated a compact passively Q-switched Nd:GGG laser with the mixed Sb2 Te3 -GO SA. Stable Q-switching operation at a central wavelength of 1066 nm was performed. The shortest single pulse width of 237 ns with repetition rate of 72 kHz and the maximum output power for Q-switched operation of 408 mW was achieved under the pump power of 4.5 W, corresponding to the optical-to-optical conversion of 9.1%.
