Graphene has attracted significant interest from researchers due to its unique physical properties. One of the graphene production methods is based on graphene oxide (GO) reduction, which can be implemented by laser irradiation. Adding organic specific dye molecules to GO leads to the formation of the larger moieties of GO crystallites. Our previous research has shown that the best quality laser-induced graphene (LIG) coating is obtained using a GO-neutral red (GO-NR) nanocomposite precursor. In this work, we performed GO reduction experiments using nanosecond (Baltic HP, Ekspla), picosecond (Atlantic, Ekspla) and femtosecond (Pharos, Light Conversion) infrared lasers irradiation. Irradiated GO-NR films were investigated by Raman spectroscopy.

It was shown that the best quality LIG was formed by nanosecond laser irradiation using 26 J/cm2 irradiation dose. When this dose was applied, the intensity ratio of Raman spectral lines I(2D)/I(G), showing the highest GO reduction quality was 0.9
