Abstract
The authors obtain values of chi (3) up to 5*10 -7 esu for non-degenerate four-wave mixing near the band edge in InSb using CW, low-power, CO laser sources. The results of a new calculation of the resonant bound-electron contribution to chi (3)( omega 1, - omega 2, omega 1) are presented. Both the magnitude and frequency dependence are in agreement with experiment, implying the dominance of the bound-electron contribution under the present conditions. This is in direct contrast with the implications of non-resonant mixing at CO2 frequencies.
