Aspects of the performance of a femtosecond laser-pulsed 3-dimensional atom probe.

Conference item

Specimen heating is shown to occur in the laser-pulsed 3-dimensional atom probe (3DAP), even in the case of femtosecond pulse lengths. This can have an impact on the spatial resolution of 3DAP analysis, due to surface diffusion, and peak temperatures must be kept sufficiently low to avoid these effects. Similarly, mass resolution can be limited in the analysis of low thermal conductivity materials, due to the slower cool-down of the specimen after the pulse. In such cases, the use of lower re...
