Abstract :
Terahertz radiation from two-color laser-produced plasma is studied with simultaneous measurements of absolute two-color phases, near-field plasma currents, and far-field THz radiation. This verifies the microscopic mechanism of terahertz radiation generation at various laser intensities.
