The method suggested by Kellogg [J. Appl. Phys. 52;
5320 (1981)] to estimate the temperature of a field emitter under laser pulsing irradiation is reconsidered in the case of a W-Re alloy. It is shown that the temperature obtained using this method is not the absolute temperature;
but;
if properly calibrated;
a value that could be considered as a good approximation of the average temperature reached by the tip when illuminated by picosecond laser pulses. © 2008 American Institute of Physics;
