Design of a High-Power Table-Top THz Free-Electron Laser

摘要

We have designed a high-power table-top terahertz (THz) free electron laser (FEL). The size of the system is estimated to be 1×2m{sup}2 by using a 600-mm-long helical undulator and a compact 4-MeV Microtron accelerator. The average THz power is calculated to be 1W with the tunable wavelength range from 200μm to 600μm (0.5 to 1.5THz). The FEL is expected to be used for the real-time imaging of security inspection.
