Query: Nondestructive imaging of an ultracold lattice gas   We demonstrate the nondestructive imaging of a lattice gas of ultracold
bosons. Atomic fluorescence is induced in the simultaneous presence of
degenerate Raman sideband cooling. The combined influence of these processes
controllably cycles an atom between a dark state and a fluorescing state while
eliminating heating and loss. Through spatially resolved sideband spectroscopy
following the imaging sequence, we demonstrate the efficacy of this imaging
technique in various regimes of lattice depth and fluorescence acquisition
rate. Our work provides an important extension of quantum gas imaging to the
nondestructive detection, control and manipulation of atoms in optical
lattices. In addition, our technique can also be extended to atomic species
that are less amenable to molasses-based lattice imaging.
