We have recently demonstrated' a third order optical susceptibility of 1.5x10 3 esu in a Hg 0.84 Cd0.16Te epilayer with small band gap at 80 K. The relaxation time for the nonlinear effect was measured to be 5 psec., and identified as the thermalization of the electrons. The observed Z(3 is ten times larger than that we reported 2 in HgTe, which then was the largest known X(3) with picosecond response times. The non-linear susceptibilities were measured with four-wave mixing experiments using a pair of Qswitched CO 2 lasers.
