基于电子束团在周期结构波导中激发的非相干衍射辐射机理,提出了调制自由电子束高次谐波在锥形双非对称光栅结构中产生相干太赫兹(THz)辐射的概念。结果表明,在该机制下,当电流密度为10 A/cm 2时,可以产生0.43 THz的辐射,效率可达0.5%。由于所需的低电流密度和相对较高的效率,该概念显示了电子束驱动太赫兹源的应用潜力。
Based on the mechanism of incoherent diffraction radiation excited by an electron bunch in a waveguide with periodic structure, this paper presents the concept of coherent terahertz (THz) radiation from the high-harmonic component of a modulated free-electron beam in a tapered two-asymmetric grating structure. The results show that in this mechanism 0.43 THz radiation can be generated with 10 A/cm2 current density, and the efficiency can reach 0.5%. Because of the low required current density and relative high efficiency, this concept shows the application potential for electron-beam-driven terahertz sources.
