G. Carelli et al., FREQUENCY MEASUREMENTS OF FAR-INFRARED LASER LINES BY MEANS OF MIM POINT-CONTACT DIODES, International journal of infrared and millimeter waves, 15(7), 1994, pp. 1347-1360
We present frequency measurements of 85 Far Infrared (FIR) laser lines
ranging from 2 748 GHz to 421 GHz. We use the heterodyne technique of
mixing FIR laser transitions and microwave radiation on MIM point con
tact diodes to determine the FIR frequencies.
