We report few-cycle THz pulses emission from a novel organic crystal 2,6-diaminopyridinium-4-nitrophenolate-4-nitrophenol (DAP + NP - NP). The observed amplitude of the THz electric field from a DAP + NP - NP crystal is comparable with that from a ZnTe single crystal under the same optical pumping conditions. Both the waveform and spectra of the THz radiation from DAP + NP - NP are similar to those from ZnTe. We conclude that a high quality DAP + NP - NP crystal would be a high potential candidate in THz generation and applications.
