Semicontinuous metals films of copper and gold were grown on different substrates by pulsed laser ablation. The resistance and transmittance of these growing metal films were monitored in situ vs film thickness. Despite diverse experimental variations, it was found that both resistance and transmittance exhibited similar behaviors. Around percolation, the resistance exhibited a sharp drop whereas the transmittance exhibited a dip. In general, the onset of percolation depended on laser fluence and substrates. Under favorable conditions, metal films as thin as 1.5 nm would percolate.
