Abstract
We demonstrated that coherently driven atomic or molecular media potentially yield strong controllable short pulses of THz radiation. The method is based on excitation of maximal coherence in an atomic or molecular gas by optical pulses and coherent scattering of infrared radiation to produce pulses of THz radiation. The pulses can reach the energies ranging from seeral nJ to μJ and time durations from several cycles to ns at room temperature.
