Abstract :
Summary form only given. The use of thin ZnTe electro-optic sensors for coherent characterization of a freely propagating terahertz beam demonstrated a bandwidth up to 37 THz. This represents a significant improvement over the previous result of 7 THz by using a GaP crystal, and also confirms the broadband nature of mid-IR radiation generated by optical rectification. With the ultrashort laser pulses of 10 fs, it is feasible to generate and detect a THz beam with a bandwidth over 40 THz.
