Abstract
Dynamic measurements of velocity and temperature yield information on the temperature distribution and the thermal thickness of the evaporation front caused by focused laser irradiation on metals. The thermal thickness of the evaporation front is inversly proportional to the steady-state velocity of the front. Direct temperature values are obtained by measuring the thermoelectric signals from thermocouple junctions of 10 μm average dimensions, located at the back side of the drilled sample. Experimental results are compared to thermal models theory and the implications concerning the drilled efficiency are considered.
