[IEEE 2019 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC) - Munich, Germany (2019.6.23-2019.6.27)] 2019 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC) - Numerical Simulations of THz Generation with two-Color Mid-Infrared Laser Pulse and Relative Phase Control

摘要： The generation of terahertz (THz) radiation by two-color laser pulse induced gas plasma is an actively researched topic since its exploration [1]. It is a tabletop, powerful spectroscopic tool in the far-infrared spectral regime. The THz spectroscopy is capable to identify chemicals in a nondestructive way [2]. It is capable to generate THz radiation by remotely more than 100m from the laser system [3], the remote sensing of the THz radiation also possible [4]. By the combination of the former mentioned features, the THz spectroscopy is a powerful tool to identify drugs, poisons and explosives with remotely in a nondestructive way.
