"Coherent THz Radiation from Plasma Oscillation Driven by Laser Pulses"

Presented by Dr. Min Sup Hur, Physics Department - UNIST Korea

Plasma, a gas of electric charges, exhibits a fundamental oscillating behavior, the plasma oscillation. Similar to the classical harmonic oscillator, but charged, the plasma oscillation is potentially an outstanding source of coherent, monochromatic radiation with high intensity and high frequency. However, harnessing the plasma oscillation and taking the radiation out of it are never trivial problems. In this presentation, I introduce one novel method to generate an isolated plasma dipole oscillation by colliding laser pulses in a plasma, eventually to obtain a quasi-narrowband, powerful THz emission. The conceptual connection of the idea to the astrophysical plasma emission is also addressed.
