Abstract: We report our results on high order harmonic mixing between two visible lasers and microwave radiations in point-contact diodes. We have observed up to the 17th harmonic mixing order between two lasers (DELTAnu = 150 GHz) and a X-band klystron in a Schottky diode. We have been able to monitor very large laser frequency differences, up to 540 GHz (almost-equal-to 1.3 nm) with a good signal to noise ratio while using a very low power microwave source (20 mW/90 GHz). These results can be improved by using stabilized lasers and phase-locked microwave sources.
