Abstract
This paper is about a gold palladium thin-film microthermocouple gate array. The gate array is fabricated by standard photolithography and sputtering technology. The sensor has been developed to characterize the energetic profile of laser power. The thermal sensor is a thin film thermocouple gate array with 16 sensing junctions per 288 micrometers . The response of Au/Pd thin-film thermocouple has been characterized, the time constant of thermocouple response is in order of 140 microsecond(s) . Furthermore, a linear graph giving the thermoelastic voltage versus the incident power laser has been obtained. Finally, the spot size and the intensity profile of laser beam have been estimated using the sensor.
