ABSTRACT
To the best of our knowledge we report the first demonstration of surface thermometry using laser-induced second-harmonic generation (SHG) on a realistic metallic surface at atmospheric pressure. The surface is probed with a pulsed infrared laser beam and the SHG signal is monitored in reflection. For metallic silver, the SHG signal is found to be temperature dependent in the 25-120 οC range. The current accuracy of the method is ∓ οC. Future work with platinum should permit the application of SHG thermometry to much higher surface temperatures.
