  Laser enhanced field evaporation of surface atoms in Laser-assisted Atom
Probe Tomography (La-APT) can simultaneously excite phtotoluminescence in
semiconductor or insulating specimens. An atom probe equipped with appropriate
focalization and collection optics has been coupled with an in-situ
micro-Photoluminescence ({\mu}PL) bench that can be operated during APT
analysis. The Photonic Atom Probe instrument we have developped operates at
frequencies up to 500 kHz and is controlled by 150 fs laser pulses tunable in
energy in a large spectral range (spanning from deep UV to near IR). Micro-PL
spectroscopy is performed using a 320 mm focal length spectrometer equipped
with a CCD camera for time-integrated and with a streak camera for
time-resolved acquisitions. An exemple of application of this instrument on a
multi-quantum well oxide heterostructure sample illustrates the potential of
this new generation of tomographic atom probe.
