D. A. B. Miller, R. G. Harrison, A. Johnston, C. T. Seaton and S. D. Smith, "Degenerate Four-Wave Mixing in InSb at 5K," Optics Communications 32, 478-480 (1980).

Reports the observation of degenerate four-wave mixing 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 approximately 1% are obtained with less than 13 mW beam powers, and higher efficiencies are predicted for improved phase-matching. This observation is important for the possible use of InSb for CW phase conjugation, and also for the detailed physics of devices based on nonlinear Fabry-Perot action
