Abstract
A continuous and tunable operation from 1.6 to 4.5 THz has been demonstrated using a difference frequency generation (DFG) scheme by using the nonlinear optical crystal 4-dimethylamino-N-methyl-4-stilbazolium-tosylate (DAST) as the DFG crystal. The scheme was based on DFG between two seeded optical parametric generators. The THz bandwidth was 2.4 GHz. A high-resolution transmission spectrum of water vapor in air was used to demonstrate the utility of this source over the above THz spectral range.
