  • Terahertz free electron superradiation from mimicking surface plasmons-two electron beams interaction within a 3-mirror quasi-Optical Cavity
    Applied Physics Letters, 2013
    Co-Authors: Ya-xin Zhang, Yucong Zhou, L. Dong, Shenggang Liu
    Abstract:

    Interaction between mimicking surface plasmons and electron beams provides a good opportunity to develop terahertz (THz) radiation sources. In this paper, such an interaction in a special 3-mirror quasi-Optical Cavity is presented and explored. The 3-mirror quasi-Optical Cavity acts as a resonant tunable system, the resonance frequency of which can be tuned by adjusting the distance between mirrors. The study demonstrated THz free electron superradiation from the interaction of mimicking surface plasmons and two electron beams that formed a resonance within the structure, with the 3-mirror Cavity enhancing the intensity of superradiation. Moreover, this system can work in the high-harmonic superradiation region with relatively high efficiency and low current density. This concept thus shows the application potential for electron-beam-driven terahertz sources.
