Figure | Pump-induced stimulated superradiant Smith-Purcell radiation (PIS-SPR) and compact device. A schematic view of the pump-induced stimulated superradiant Smith-Purcell radiation (PIS-SPR) device, which consists of the electron pre-bunching, electron-compression and harmonic-emission section. Based on PIS-SPR, the free electron beam is well bunched and ultra-narrow spectral linewidth at THz frequency region has been observed.
