Abstract
Far-infrared tunable radiation is produced in a four-level laser system by using a pumping means for exciting population from the lowest level of the system to the upper level of a laser transition to create a population inversion between the upper and lower levels of the laser transition and a laser beam which is nearly resonant with the lower level of the laser transition and a fourth level of the system. The laser beam shifts the lower level of the laser transition according to the dynamic Stark effect to provide for tuning of the far-infrared radiation.
