The development of widely-tunable monochromatic THz sources is described. These sources are based on difference-frequency generation (DFG) in GaSe, ZnGeP/sub 2/, and GaP, respectively. Using a GaSe crystal the output wavelength was tuned in the range of from 58.2 /spl mu/m to 3540 /spl mu/m (from 172 cm/sup -1/ to 2.82 cm/sup -1/) with the peak power reaching 209 W. On the other hand, based on DFG in a ZnGeP/sub 2/ crystal the output wavelength was tuned in the ranges of 83.1-1642 /spl mu/m and 80.2-1416 /spl mu/m for two phase-matching configurations, respectively. The output power reached 134 W. Finally, using a GaP crystal the output wavelength was tuned in the range of 71.1-2830 /spl mu/m whereas the highest peak power was 15.6 W.
