Abstract
We have observed phase-conjugate signals in n-type Hg1-x Cdx Te through bandgap-resonant degenerate fourwave mixing by using a chopped cw-CO2 laser pump operating at 10.6 µm and ~1 W/cm2. The observed signals are attributed to the strong resonant third-order nonlinearity [χ(3)] arising from the electron-hole pair production the pump laser. Our data translate into a value of χ(3)~3 × 10-2 esu, which is in good agreement with that calculated using the model of Jain et al. [Appl. Phys. Lett. 35, 494 (1979)].
