La note décrit les résultats préliminaires obtenus avec des diodes Schottky utilisées comme mélangeuses dans la région des 10.6 μm. Le battement entre deux lasers à CO2 a été observé ainsi que des effets de directivité et l'influence de la polarisation de la diode. À 10.6 μm une sensibilité de la détection de 1 V/W a été obtenue.The letter describes preliminary results on Schottky diode mixers at 10.6 μm. We observed the beat note between two CO2 radiation lasers. The detection dependence is reported with respect to the directivity and the d.c.bias. A sensitivity of 1 V/W was obtained at 10.6 μm.
