Abbreviated Series Title The effects of varying the laser pulse-energy of a picosecond laser used in pulsed-laser atom- probe (PLAP) tomography of an as-quenched Ni-6.24 Al- 9.64 Cr at.% are assessed based on the quality of the mass spectra and the compositional accuracy of the technique. PLAP tomography improves mass resolution, increases the signal-to-noise (S/N) ratio, and improves compositional accuracy, compared to pulsed-voltage atom-probe tomography (APT). Experimental evidence suggests that Ni2+, Al2+ and Cr2+ ions are formed by post-ionization of singly charged ions, as well as by a thermally-activated evaporation process. An analysis of the detected noise levels reveals that there is no significant steady-state heating of the Ni-6.24 Al- 9.64 Cr at.% tips during PLAP tomography for properly chosen instrument parameters.
