Abstract :
Femtosecond optical pulse train is produced by the reflections on the step mirror which consists of two D-shape mirrors. The THz radiation is generated from the photoconductive antenna pumped by the pulse train and the frequency tuning is achieved by simply moving one of the D-shape mirrors in order to vary the step difference.
