Quantum oscillations of spin-flip Raman scattering in InSb

Calculations have been made of the spontaneous cross section of spin-flip Raman scattering in InSb. The electron occupancy of the conduction-band Landau states is accounted for in order to evaluate the cross section for the resonant conditions that occur for 5 mu m pumping at low magnetic fields. It is shown that quantum oscillations in the cross section are a major cause of irregularities observed in spin-flip Raman-laser output powers. Calculations of the cross sections for double-cyclotron and double-cyclotron spin-flip scattering are also presented.
