Abstract :
We have designed a high-power table-top terahertz (THz) free electron laser (FEL). The size of the system is estimated to be 1times2 m2 by using a 600-mm-long helical undulator and a compact 4-MeV Microtron accelerator. The average THz power is calculated to be 1 W with the tunable wavelength range from 200 mum to 600 mum (0.5 to 1.5 THz). The FEL is expected to be used for the real-time imaging of security inspection.
