A quantum theory of nondegenerate four-wave mixing is developed and applied to study a highly excited semiconductor resonator operating below or near the laser threshold. It is found that total carrier-density pulsations allow coherent effects in semiconductors despite the rapid decay of the electron-hole correlations. The output spectrum for a nondegenerate four-wave mixing intracavity experiment is computed and squeezing in the sidemode spectrum is predicted.
