[IEEE 2019 44th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz) - Paris, France (2019.9.1-2019.9.6)] 2019 44th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz) - Numerical Study of CO Laser Down-Conversion into the THz Range With ZnGeP <sub/>2</sub> crystal

摘要： Difference frequency generation of rotational-vibrational lines of nonselective CO laser in ZnGeP2 crystal was numerically studied. It was shown that a great number of difference frequency lines can densely cover spectral range from 50 to 1000 (cid:2)m and even up to 5000 (cid:2)m. An influence of ZnGeP2 crystal absorption on THz generation was studied.
