Scanning probe microscope (SPM) is used not only for measuring the micro profiles of surfaces, but also for nano ultraprecise machining and atom manipulation now.

The converters could apparently also be used for optical manipulation of atom-sized objects, inexpensive ultra-high resolution microscopic imaging, and possibly even table-top particle accelerators.

The making and manipulation of entangled atom-photon pairs are useful for, e. g., high-precision interferometry and quantum information science.
