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

Key Points

• Investigate the generation of broadband terahertz radiation by an optical pulse in nonlinear uniaxial crystals.
• Utilized numerical modeling to simulate the generation process.
• Focused on how optical pulses behave in nonlinear uniaxial crystals.
• Identified the formation of a stable optical-terahertz soliton during the generation process.
• Observed an additional broadband terahertz signal alongside the soliton.
