Abstract: We generated widely tunable terahertz (THz) waves using difference-frequency generation (DFG) in a configurationally locked polyene (CLP) 2-[3-(4-hydroxystyryl)- 5, 5-dimethylcyclohex-2-enylidene]malononitrile (OH1) crystal. The two waves generated by a KTiOPO4 (KTP) optical parametric oscillator (OPO) were used to pump the OH1 crystal. The maximum output energy of the THz wave was 604 pJ/pulse. Widely tunable THz waves were successfully generated from 0.5 to 10 THz by using difference-frequency generation source.
Keywords: Nonlinear optical materials, Difference-frequency generation, OH1 crystal
Acknowledgments: The authors are greatly indebted to Noboru Fukasaku for Synthesis of high purity OH1.
