A method is proposed for producing atom gratings having period $\lambda -4$ and $\lambda -8$ using optical fields having wavelength $\lambda$. Counterpropagating optical fields drive Raman transitions between ground state sublevels. The Raman fields can be described by an effective two photon field having wave vector 2 k, where k is the propagatio
