The emergence of quasi-stable soliton-like modes during the generation of terahertz radiation by an optical pulse

Based on numerical modeling, the process of generating broadband terahertz radiation by an optical pulse in a nonlinear uniaxial crystal was investigated. It was shown that the generation process is accompanied by the formation of a stable optical-terahertz soliton, as well as a broadband terahertz signal additional to the soliton.
