The plasma characterization has been obtained giving providing the involved ion species and charge states, and the average temperature and density. Increasing the laser fluence the ablation yield, the plasma density and temperature, the velocity of the emitted particles and the emitted mass yields increase. Due to the laser heating a graphene oxide reduction is also observed. The oxygen is emitted as elemental and as part of different functional groups. A strong dehydration and dehydrogenation occur due to the laser pulse energy deposition, testifying the high content of water and hydrogen possessed by graphene oxide.
