Abstract
An instability of a coherent state bf Wannier-Mott excitons sustained by a resonant pump wave is analyzed. The instability involves a spatia lly periodic stratification with a period L approximately L(ex) = (HBA R/mgamma)1/2, where m is the effective exciton mass, and gamma is the reciprocal exciton lifetime.
