It is suggested that far-infrared radiation can be generated by difference-frequency mixing of surface waves on an interface between metal and nonlinear crystal. Particularly, the power of FIR generated on Al-GaAs interface is catculated in the case of noncollinear phase matching. In this calculation, the imaginary part of dielectric constants is considered.
