| Research Abstract |
We report on the demonstration of an effective and widely tunable terahertz (THz)-wave generation using difference frequency generation (DFG) in an organic 4-dimethylamino-N-methyl-4-stilbazolium tosylate (DAST) by optimization of the pumping wavelength. We calculated the Type 0 phase-matching condition of DAST-DFG THz-wave generation over an ultrawide band. To satisfy phase-matching conditions over the whole THz-wave region, two pump wavelengths were controlled independently. A comparison of the calculated and experimental results established the optimum phase-matching condition of DAST-DFG.
