Abstract : The manuscript summarizes work done on atom mirrors in the Atom Optics group between 1991 and 2000. Most of the work concerns mirrors for Rb atoms using evanescent waves. An important goal has been the realization of high quality optical elements for atom optics, particularly coherent atom mirrors. It is necessary to reduce spontaneous emission by enhancing the intensity of the evanescent wave as well as to understand the influence surface roughness. It is also possible to introduce a controlled periodic corrugation producing diffraction at both normal and grazing incidence. We have used the apparatus to make a surface nanoprobe sensitive to van der Waals interactions between an atom and the surface. The manuscript describes interference measurements on bouncing atoms which use velocity selective Raman Transitions.
