使用两个步进可调谐CO2激光器，我们观察到在双折射三元半导体ZnGeP2中通过非线性混频产生相位匹配的频率70 <ν<110 cm−1。在83.37 cm−1处观测到的功率为1.7 μW，使用Ge：Ga探测器得到的信噪比为1000。与可调谐光学激光器相结合，该技术应该产生用于高分辨率光谱学的亚毫米波辐射的可调谐源。
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.
