Effects of Quasi-Phase Matching in Gases when Generating Terahertz Radiation in Two-Color Laser Fields

Abstract

Results are presented from numerical studies of generating terahertz radiation during interaction between a two-color laser field and gas media created by argon jets. The laser field is formed by linearly polarized first (ω) and second (2ω) harmonics of a Ti:Sa laser. The effect quasi-phase matching has on the efficiency, angular-frequency spectra of the terahertz radiation is shown.
