    "abstract": "We discuss a method to select the velocities of ultra-cold atoms with a\nmodified Fabry-Perot type of device made of two effective barriers and a well\ncreated, respectively, by blue and red detuned lasers. The laser parameters may\nbe used to select the peak and width of the transmitted velocity window. In\nparticular, lowering the central well provides a peak arbitrarily close to zero\nvelocity having a minimum but finite width. The low-energy atomic scattering\noff this laser device is parameterized and approximate formulae are found to\ndescribe and explain its behaviour.",
