Electro-optical sampling (EOS) of ultrabroadband terahertz (THz) radiation with the help of ultrashort 530 nm fs-laser pulses is reported. The THz pulses are generated by exciting a surface emitter (InAs) with a parabolic fiber laser amplifier delivering 100 fs pulses at a repetition rate of 75 MHz and an average power of 10 W at 1060 nm. The pulses are frequency doubled to 530 nm for gating and BaTiO3 is used as the detector crystal.
