Recent Studies of Intense-Laser-Driven X-ray and Terahertz Radiation Sources at the Insitute of Physics, CAS
Abstract
Hard Kα x-ray source profile and intense Terahertz radiation from femtosecond laser-plasma interactions are studied. When a preplasma is presented, a weak halo surrounding a bright spot is observed in the x-ray source. The x-ray photons in the halo are mainly excited by the fast electrons that flow laterally near the target surface. Intense Terahertz radiation has been observed in the laser specular direction. The pulse energy of the radiation reaches tens of μJ/sr.
