By exploiting the Rabi-flopping-induced coherent density oscillations in a weakly dc-biased quantum well, we describe a new method for producing very intense (roughly kilovolts per centimeter), tunable terahertz transients. We achieved tunability by simply varying the area of the input optical pulse.
