We report few-cycle THz pulses emission from a novel organic crystal 2,6-diaminopyridinium-4-nitrophenolate-4-nitrophenol (DAPNPNP). The observed amplitude of the THz electric field from a DAPNPNP 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 DAPNPNP are similar to those from ZnTe. We conclude that a high quality DAPNPNP crystal would be a high potential candidate in THz generation and applications.
