Electrooptical sampling of ultra-broadband terahertz (THz) radiation with the help of ultra-short 1060-nm pulses is reported for the first time. 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. ZnTe and GaP crystals are used for detection and their velocity mismatch is compared at 800 nm and 1060 nm.
