中文摘要	The organic nonlinear optical (NLO) crystal OH1 (2-(3-(4-hydroxystyryl)-5,5-dimethylcyclohex-2-enylidene) malononitrile) was grown by the seeded solution growth method with size up to 11 x 11 x 10 mm(3). The cooling rate would affect the crystal formation and lead to the different shapes of OH1 crystals. The hydrogen-bond interactions between the OH1 molecules played a prominent influence on the molecular alignment and the direction of crystal growth. Furthermore, the OH1 crystals grown horn the seeds on different orientations would form different morphologies. X-ray rocking curve showed good quality of the grown crystals. Continuous stiffness measurement showed that the hardness of the OH1 (100) and (111) plane was about 0.67 GPa and 0.51 GPa, while the Young's modulus was about 9.68 GPa and 11.91 GPa, respectively. The transmission spectra in the range of 0.5-20 mu m was measured and there was a transmission window appearing in the mid-infrared waveband of 4-6 mu m. With the OH1 crystal obtained, continuous THz wave radiation ranging from 0.25 to 3.0 THz was generated by an optical rectification method, which was two times as large as that generated from ZnTe in the low frequency band.
