We have developed a high average power picosecond laser system, named QUADRA-T, dedicated to intense terahertz (THz) pulse generation. QUADRA-T is a chirped pulse amplification laser equipping Yb:YAG thin-disk amplifier. The Yb:YAG thin-disk regenerative amplifier at room temperature provides 10 mJ pulses at a repetition rate of 1 kHz. Duration of a recompressed pulse is 1.3 ps. By employing this picosecond pulse as a pump source, THz pulse of the center frequency of 0.3 THz with a few micro joules energy has been obtained by the optical rectification in Mg-LiNbO $_{3}$ crystal.
