    "abstract": "Using a canonical pump-probe experimental technique, we studied the terahertz\n(THz) waves generation and detection via optical rectification and mixing in\nCzochralski-grown periodically poled Mg:Y:LiNbO3 (PPLN) crystals. THz waves\nwith frequencies at 1.37 THz and 0.68 THz as well as 1.8 THz were obtained for\nPPLN with nonlinear grating periods of 0.03 and 0.06 mm, respectively. A\ngeneral theoretical model was developed by considering the dispersion and\ndamping of low frequency phonon-polariton mode. Our results show that THz waves\nare generated in forward and backward directions via pumping pulse\nrectification. The generated THz waves depend on the spectral shape of the\nlaser pulses, quasi-phase mismatches and dispersion characteristics of a\ncrystal.",
