Abstract
We have observed a new component in the signals produced by degenerate four-wave mixing of 5-nsec optical pulses by the -line resonances of sodium vapor. This component is comparable in intensity to that previously observed from a grating pattern of excited sodium atoms, but arises rather from a grating of coherently aligned (but not optically pumped) ground-state atoms. This component exists when there are no spatial intensity beats between input waves.
