Freely propagating terahertz pulses have been superimposed on a detection crystal leading to their mutual annihilation. An extinction ratio as good as 10:1 is found. The interference pattern represents the sum of the pulses, as measured individually, with high fidelity. Its application for high-resolution spectroscopy and optical computing are discussed. © 2001 American Institute of Physics.
