Properties of point-contact warm carrier devices, when used as harmonic mixers in the CO2 laser frequency region, were investigated. Harmonic mixing experiments were carried out by using the 8.93GHz microwave source and the two CO2 lasers operating at different frequencies. The results showed that the point-contact warm carrier device works as a detector and mixer at CO2 laser frequency as does the W-Ni point-contact MOM diode.
