Laser-metal interaction employed greater advantages to the performance of devices for electronics and optoelectronics devices. Silver (Ag) thin films were deposited onto silicon (Si) and glass substrates using direct current (DC) magnetron sputtering system. An under-layer, chromium (Cr) thin films that act as an adhesive layer were deposited on the glass substrate. Laser treatments on the samples were carried out at different laser energy under N2 ambient in a pressure cube. It is found that the electrical, optical and morphological properties improved after laser treatment process. Laser-treated Cr/Ag at 165 mJ shows a low electrical resistivity of 1.21 × 10-6 Ω-cm. Optical reflectance and the transmittance increases from 1.675% and 1.636% to 7.256 % and 7.204 % respectively at 470 nm. Meanwhile, surface roughness has shown a value of 5 nm for the sample treated at a maximum laser energy.
