A pulsed, coherent, spin-flip Raman experiment is proposed. Calculations show that if narrow pulses are used to drive the spin system in InSb via the Raman coupling, the equivalent of an NMR

-pulse experiment may be achieved. The free induction decay signal is expected to be about 10
-6J/pulse and might serve as an intense, pulsed, magnetically tunable source of far-infrared (IR) generation.
