Difference frequencies up to 85 MHz were detected by mixing two different CO2-laser beams coupled to the diode with an integrated bow-tie antenna. The dependence of the beat signal on bias voltage, laser power and polarization of the infrared laser radiation was determined.en© Springer-Verlag 1996Journal article003000723410.1007/BF01095263A1996VA196000082-s2.0-003021669374831Fumeaux, C.
