Passive Q-Switching with Graphene Saturable Absorber in Nd:YAG Operating at 1064nm
A graphene-PVA film is fabricated by using polyvinyl alcohol(PVA), which provides excellent mechanical property and easy operation. Based on the numerous advantages of graphene in optical and mechanical characteristics,Graphene was used as absorber with passively Q-switched Nd:YAG solid laser in our experiment. Furthermore, there are no changes in the structure and characteristics of graphene. Inserting our graphene-PVA SA mirror to the Nd: YAG laser, we ultimately get that the single pulse energy is about 7.68μJ, and that the shortest pulse width is about 640ns. The experiment results prove that our graphene-PVA SA mirror is feasible and suitable for Q-switched lasers.
