Times Cited Count：25 Percentile：78.49(Optics)We have developed a 1 kHz repetition picosecond laser system dedicated for intense terahertz (THz) pulse generation. The system comprises a chirped pulse amplification laser equipped with a Yb:YAG thin-disk amplifier. At room temperature, the Yb:YAG thin-disk regenerative amplifier provides pulses having energy of over 10 mJ and spectral bandwidth of 1.2 nm. The pulse duration achieved after passage through a diffraction grating pair compressor was 1.3 ps. By employing this picosecond laser as a pump source, THz pulses having a peak frequency of 0.3 THz and 4 
J of energy were generated by means of optical rectification in an Mg-doped LiNbO
crystal.

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 crystal.

The Yb:YAG thin-disk regenerative amplifier at room temperature provides pulses with energy over 10 mJ and spectral bandwidth of 1.2 nm at a repetition rate of 1 kHz. In a pulse compressor, the laser pulse is compressed to be 1.3 ps. By employing this picosecond pulse as a pump source, THz pulses at the center frequency of 0.3 THz with energy over a few microjoules have been generated at 1 kHz repetition rate by the optical rectification in Mg-LiNbO crystal.
