Abstract :
We observed electromagnetic wave in the terahertz (THz) frequency range from a Ti foil excited by tabletop terawatt (T-cube) laser pulses. We analyzed the polarization characteristics of the THz wave. It is found that the polarization of the radiated sub-terahertz signals was p-polarization, which is independent on the pump laser polarization.
