A terahertz (THz) generation and detection setup based on pump‐probe scheme is presented. THz pulses are generated and detected successfully using nonlinear optical rectification of high power femtosecond laser pulses and electro‐optic sampling. 3 THz available spectrum range is obtained for the setup. The use of THz pulses for spectroscopy is tested by measuring the absorption spectrums of water in air and dry nitrogen, respectively. The measurement results show the setup has a high potential of THz spectroscopy. © 2009 Wiley Periodicals, Inc.
