Abstract

We propose an optical grating for matter waves that separates molecules depending on whether their interaction with the light is conservative or dissipative. Potential applications include fundamental tests of quantum mechanics, measurement of molecular properties, and the ability to selectively prepare matter waves with different internal temperatures.
