Summary:
We have developed a laboratory-scale users facility with a compact terahertz (THz) free electron laser (FEL). The FEL operates in the wavelength range of 100 ? 1200 μm, which corresponds to 0 ? 3.3 THz. THz radiation from the FEL shows well collimated Gaussian spatial distribution and narrow spectral width of . Δλ/λ ~ 0.003, which is Fourier transform limited by the estimated pulse duration of 20 ps. The main application of the FEL is THz imaging for bio-medical researches. We are developing THz imaging techniques by 2-dimensional (2-D) scanning, single pulse capturing with the electro-optic method, and 3-D holography. In this paper we will show and discuss the main results of THz imaging with the different methods by using the KAERI compact FEL.
