Bright, tunable sources of narrow-band THz radiation are highly desirable for studies of low energy excitations of various systems such as phonons, strongly correlated electron systems, and the rotational and vibrational states of molecules. Techniques developed so far to obtain narrow-band THz pulses include mixing chirped optical pulses in a photoconductive switch; optical rectification of shaped pulses; and optical rectification in quasi-phase matching nonlinear crystals.
