STIMULATED ANTI-STOKES SPIN-FLIP RAMAN SCATTERING IN InSb

Abstract

We report the first observation of tunable stimulated anti‐Stokes spin‐flip Raman (SFR) scattering in InSb. Using a CO₂ laser at 10.6μ as the pump, the anti‐Stokes SFR laser is tunable from ∼10.0 to ∼9.4μ, and the concurrently appearing Stokes SFR laser is tunable from ∼11.3 to 12.2μ by changing the magnetic field from ∼30 to ∼65 kG.
