Coherent effects in spin-flip light scattering

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
\pi/2
-pulse experiment may be achieved. The free induction decay signal is expected to be about 10
^-6
J/pulse and might serve as an intense, pulsed, magnetically tunable source of far-infrared (IR) generation.
