We propose a scheme that allows us to Fourier-synthesize arbitrarily shaped periodic potentials for atoms. The method is based on the dispersion connected with higher order multiphoton Raman processes, where a suitable combination of laser frequencies eliminates unwanted standing wave effects. Future application of the scheme could range from blazed atomic beam splitters up to atomic quantum ratchets.
