The effects of the fluence and irradiance on the ability to write controlled resistance, conductive tracks using nanosecond laser pulses were studied. Two spot sizes and a large range of fluences were used to determine the optimal parameters to achieve controlled resistance. The resistance of the lines was determined using a digital ohmmeter. Optical micrographs were used to obtain the linewidths of the laser-written tracks, while profilometer scans and SEM were used to determine the ablation depths.
