Abstract

A facility to generate high-intensity, ultrashort pulses of broad-band far-infrared radiation has been assembled and tested at Stanford. The device uses sub-picosecond relativistic electron bunches to generate coherent radiation through transition or synchrotron radiation in the far-infrared (FIR) regime between millimeter waves and wavelengths of about 100 micrometers and less. Experimental results show a peak radiation power of greater than 0.33 MW within a microbunch and an average FIR radiation power of 4mW. The average bunch length of 2856 microbunches within a 1 microsecond(s) ec macropulse is estimated to be about 480 fsec. Simulations, experimental setup and results will be discussed.
