Abstract

Tunable stimulated Stokes, second-Stokes and anti-Stokes Raman scattering have been studied in InSb pumped with short pulses of 5.3 mu m radiation. Very high power levels (700 W) and conversion efficiencies (45%) have been observed for the tunable Stokes emission, and confirmed by measurements of the power depletion of the pump radiation. Stimulated Stokes emission was observed at magnetic fields as low as 5 kG, well below the quantum limit condition, and exhibited a low-field oscillatory variation of the power output due to stimulated spin-flip transitions between high-quantum-number Landau levels.
