论文摘要
提出了使用两个中等强度激光和中等相对论电子束的THZ辐射方案。在该方案中，激光遇到共同传播的相对论电子束，并通过两播衰变激发等离子片。激发的等离子将发射THZ辐射，并通过拉曼散射与第二激光相互作用。我们的估计表明，泵激光器对THZ辐射的无erna-fre-PATH比汤姆森散射短得多。提出了出于实际利益的物理参数。
A scheme of THz radiation using two moderately intense lasers and a moderately relativistic electron beam is proposed. In the scheme, a laser encounters a co-propagating relativistic electron beam, and excites plasmons via the two-plasmon decay. The excited plasmons will emit the THz radiations, interacting with the second laser via the Raman scattering. Our estimation suggests that the mena-free-path of the pump laser to the THz radiation is much shorter than the Thomson scattering. The physical parametes for practical interests are presented.
