Title: Phase-matched submillimeter wave generation by difference-frequency mixing in ZnGeP2
Abstract:Using two step-tunable CO2 lasers, we have observed phase-matched generation of frequencies 70 <ν<110 cm−1 by nonlinear mixing in a birefringent ternary semiconductor, ZnGeP2.

An observed power of ∼1.7 μW at 83.37 cm−1 gave a signal-to-noise ratio of ∼1000 with a Ge:Ga detector. In combination with tunable optical lasers, this technique should yield a tunable source of submillimeter wave radiation for high-resolution spectroscopy.Read More
