It is shown that a three-band, nonparabolic, model for zinc-blende semiconductors provides a universal curve for the frequency dependence of the two-photon coefficient, whose magnitude differs between semiconductors by the factor (Eg np32)-1. Good agreement is obtained with reported coefficients at 300°K for InSb, Hg1-xCdxTe, GaAs, and CdTe. © 1979 The American Physical Society.
