Query: Atom trapping in a bottle beam created by a diffractive optical element   A diffractive optical element (DOE) has been fabricated for creating blue
detuned atomic bottle beam traps. The DOE integrates several diffractive lenses
for trap creation and imaging of atomic fluorescence. We characterize the
performance of the DOE and demonstrate trapping of cold Cesium atoms inside a
bottle beam.
