THz emission from organic cocrystalline salt: 2, 6 diaminopyridinium 4 nitrophenolate 4 nitrophenol.
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.
