Abstract :
In this paper we report a high power THz transmitter operating at 1 kHz repetition rate. This kHz repetition rate gives a high signal-to-noise ratio, which is essential for quantitative study of high-field semiconductor physics. The transmitter is an undoped GaAs wafer with aluminum electrodes separated by a 3 cm gap. The bias to the antenna is provided by a high voltage pulse generator producing 2 μs pulses with a peak voltage of up to 40 kV. The THz antenna is illuminated at normal incidence by 150 fs, 800 nm pulses from a Clark-MXR Ti:Sapphire regenerative laser amplifier system running at 1 kHz
