N2 - In the work presented, the polymer-graphene-gold composites obtained by the methods of chemical vapor deposition and pulsed laser ablation (PLA) are studied. The morphological and optical properties of the given samples are studied in detail. It is shown that with an increase in the number of laser pulses in the PLA method, the metal coating transforms from separate small gold particles to a continuous cover with the presence of large nanoparticles. It is shown that a change in the gold film thickness influences significantly the efficiency of plasmon attenuation of a signal: with an increase in the average mass thickness, the effect increases and reaches its maximal value at film thickness of 6 nm. It is shown that the most intense plasmon absorption occurs in the wavelength range from 550 to 750 nm. A further increase in the thickness of metal coating decreases sample transparency in the studied range and does not affect the intensity of plasmon absorption and scattering.
