Abstract

We have observed phase-conjugate signals in n-type Hg1−xCdxTe through bandgap-resonant degenerate four-wave 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 by 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)].
