Abstract
Tunable spin-flip Raman scattering has been observed in Hg0.766Cd0.234Te using several CO2 laser lines near 9.5 μm to pump the crystal. The Stokes component with a maximum power output of about 1 W was tunable between 15 and 68 cm−1 from the pump frequency with magnetic fields between 4 and 21 kG. This corresponds to an average tuning rate of 3.4 cm−1/kG. The extrapolated zero-field g factor was measured to be |79|±3 yielding a conduction band-edge effective mass ratio of 0.0101±0.0005. Several factors suggest that the tunable radiation was stimulated.
