| Abstract: | We report the observation of degenerate four-wave mixing in InSb at 5 K using a cw CO laser operating in the spectral region just below the bandgap energy, where strong self-defocusing and optical bistability have previously been seen. Conversion efficiencies of ≈1% are obtained with <13 mW beam powers, and higher efficiencies are predicted for improved phase-matching. |
