4-wave mixing has been demonstrated in room temperature germanium using a TEA CO2 laser (9.3 µm) and an optically pumped NH3 laser (12.8 µm) as radiation sources. Non-collinear phase matched emission near 7 µm has been observed with a mixing efficiency close to the calculated value. The extension of this mixing process to generate wavelengths in the important region near 16 µm is discussed. © 1978.
