    Radiation Emission from Plasmas
    Plasma is a gaseous collection of charged particles, and intrinsically, an oscillator, having a potential as an ultra-powerful source of electromagnetic radiations.

    • Utilizing the laser-plasma systems as novel Terahertz sources with ultra-intense field strength beyond GV/cm, and selective, high frequency in 1 – 30 THz.
    • A new way of understanding the unsolved, mysterious astrophysical radio emission from deep space and the Sun in terms of plasma emission.
