High-power terahertz generation via two-color laser filamentation and real-time terahertz imaging

摘要

We generate terahertz radiation via two-color laser filamentation with average output power of 1.4 mW and peak fields of 4.4 MV/cm. We also introduce a real-time, uncooled, cost-effective microbolometer camera for terahertz profiling and imaging.
