THz light amplification by an visible light laser in the presence of the plasma density gradient. (arXiv:2003.08231v1 [physics.optics])

S. Son
A new mechanism for the THz light amplification is identified ina non-resonant Raman scattering between the THz light and a visible light lasers. The non-resonant scattering normally does not exchange the energy between E \&M fields, but the presence of the plasma density gradientcreates an condition in which a visible light laser could transfer its energy into a tera-hertz (THz) light via the laser-plasma interaction. The gain per length could reach 100 (1000) per centimeter for the THz light (far infra-red light) amplification.
